Page 61: Connection Of Motor With Encoder (Vector Control)
Connection of motor with encoder (vector control) Connection of motor with encoder (vector control) Using encoder-equipped motors together with a vector control compatible option enables speed, torque, and positioning control operations under orientation control, encoder feedback control, and full-scale vector control. This section explains wiring for use of the FR-A8AP.
Page 62 Connection of motor with encoder (vector control) Switches of the FR-A8AP Differential line driver (initial status) • Encoder type selection switch (SW3) Selects either the differential line driver or complementary setting. It is initially set to the differential line driver. Switch its position according to the output circuit.
Page 63 Connection of motor with encoder (vector control) Encoder cable • As the terminal block of the FR-A8AP is an insertion type, cables need to be treated when the encoder cables of the inverter are crimping terminals. Cut the crimping terminal of the encoder cable and strip its sheath to make its cable wires loose.
Page 64 Connection of motor with encoder (vector control) Instructions for encoder cable wiring • Use shielded twisted pair cables (0.2 mm or larger) to connect the FR-A8AP. For the wiring to the terminals PG and SD, use several cables in parallel or use a thick cable, according to the wiring length. To protect the cables from noise, run them away from any source of noise (such as the main circuit and power supply voltage).

Page 69: Electro-Magnetic Interference (Emi) And Leakage Currents
Electro-magnetic interference (EMI) and leakage currents Electro-magnetic interference (EMI) and leakage currents 3.1.1 Leakage currents and countermeasures Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current.
Page 70 Electro-magnetic interference (EMI) and leakage currents Install a molded case circuit breaker (MCCB) on the power receiving side to protect the wiring at the inverter input side. Select an MCCB according to the inverter input side power factor, which depends on the power supply voltage, output frequency and load.
Page 71 Electro-magnetic interference (EMI) and leakage currents Noise Countermeasure propagation path When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g. instruments, receivers and sensors, are contained in the enclosure that contains the inverter or when their signal cables are run near the inverter, the devices may malfunction due to by air-propagated electromagnetic noises.
Page 72: Power Supply Harmonics
Power supply harmonics Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power factor correction capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.
Page 73: Power-Off And Magnetic Contactor (Mc)
Power-OFF and magnetic contactor (MC) Power-OFF and magnetic contactor (MC) Inverter input side magnetic contactor (MC) On the inverter input side, it is recommended to provide an MC for the following purposes: (Refer to page 20 for selection.) • To disconnect the inverter from the power supply at activation of a protective function or at malfunctioning of the driving system (emergency stop, etc.).

Countermeasures against deterioration of the 600 V class motor insulation Countermeasures against deterioration of the 600 V class motor insulation In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 600V class motor, the surge voltage may deteriorate the insulation.

Page 76 Checklist before starting operation Refer Check Checkpoint Countermeasure to page by user When using a switching circuit as shown below, chattering due to mis- configured sequence or arc generated at switching may allow undesirable current to flow in and damage the inverter. Mis-wiring may also damage the inverter.
Page 77: Failsafe System Which Uses The Inverter
Although Mitsubishi Electric assures the best quality products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to the machine when the inverter fails for some reason. Also at the same time consider the system configuration where a failsafe from outside the inverter, without using the inverter, is enabled even if the inverter fails.
Page 78 Failsafe system which uses the inverter (b) Checking the inverter operating status by the inverter operation ready completion signal Power supply Operation ready signal (RY signal) is output when the inverter power is ON and the inverter becomes operative. Check if the RY signal is output after powering ON the inverter.
Page 79 Failsafe system which uses the inverter Backup method outside the inverter Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure status of the inverter itself. For example, if an inverter CPU fails in a system interlocked with the inverter's fault, start, and RUN signals, no fault signal will be output and the RUN signal will be kept ON because the inverter CPU is down.

Deceleration time can be reduced by suppressing the stall prevention (overvoltage) (oL).
Page 619: Slip Compensation
(G) Control parameters Overcurrent prevention function (Pr.662) • The overcurrent prevention function is valid under V/F control and Advanced magnetic flux vector control. • Increased magnetic excitation rate is lowered automatically when the output current exceeds Pr.662 at the time of increased magnetic excitation deceleration.
Page 620: Encoder Feedback Control
(G) Control parameters 5.16.14 Encoder feedback control Magnetic flux Magnetic flux Magnetic flux By detecting the rotation speed of the motor with the speed detector (encoder) and feeding it back to the inverter, output frequency of the inverter is controlled to keep the speed of the motor constant even for the load change. Vector control compatible option is required.
Page 621 (G) Control parameters Selection of encoder feedback control (Pr.367) • When a value other than "9999" is set in Pr. 367 Speed feedback range, encoder feedback control is valid. Using the set point (frequency at which stable speed operation is performed) as reference, set the higher and lower setting range.
Page 622: Droop Control
(G) Control parameters 5.16.15 Droop control Magnetic flux Magnetic flux Magnetic flux Sensorless Sensorless Sensorless Vector Vector Vector This is a function to give droop characteristics to the speed by balancing the load in proportion with the load torque during the Advanced magnetic flux vector control, Real sensorless vector control, vector control, and PM sensorless vector control.
Page 623 (G) Control parameters Droop control • Droop control is enabled for Advanced magnetic flux vector control, Real sensorless vector control, vector control, and PM sensorless vector control. • Output frequency will change depending on the size of the current for torque with the droop control. Set % of the droop amount of rated torque with rated frequency (motor speed in case of Pr.288 = "10, 11") as a reference for the droop gain.
Page 624 (G) Control parameters Droop control break point setting (Pr.994, Pr.995) • By setting Pr.994 and Pr.995, break point (1 point) can be set up for the droop compensation frequency. Setting a break point allows the inverter to raise the droop compensation frequency for light-load (no load) operation without raising it for heavy-load operation.
Page 625: Speed Smoothing Control
(G) Control parameters 5.16.16 Speed smoothing control There are times where the vibration due to mechanical resonance affect the inverter, making the output current (torque) unstable. In such case, vibration can be decreased by reducing the deviation in the output current (torque) by changing the output frequency.
