Panasonic MINAS A6B Series Reference Specifications page 63

[1] When the servo driver uses single phase power supply for sizes A - D, connect the servo driver to the
terminals L1, L3 of main power supply input. Do not connect anything to the terminal L2.
[2] Insert the connector securely until it is locked.
[3] Make sure to use an insulation coated crimp terminal when connecting to each terminal on the
terminal block.
[4] For models with terminal block covers, the terminal block cover is screwed. When wiring to the
terminal block, unscrew these screws to uncover the cover. Please tighten the cover fixing screw to
0.19 - 0.21 N · m or less, and only tighten the terminal block cover 2 (black) of size H to less than 2.0
- 2.5 N · m torque.
[5] Apply the power supply of the voltage indicated on the nameplate.
[6] Do not reverse-connect the power input terminals (L1, L2, and L3) and the motor output terminals (U,
V, and W).
[7] Do not connect the motor output terminals (U, V, and W) to ground or short out them.
[8] Power connector XA , XB , XC , XD , and the terminal block, are supplied with voltage, so do
not touch them. There is a danger of electric shock.
[9] Suitable for use on a circuit capable of delivering not more than 5000 rms symmetrical amperes,
below the maximum input voltage of the product.
[10] An AC servomotor, unlike an induction motor, cannot change the rotation direction by exchanging
three phases.
Make sure to coincide the motor output terminals (U, V, and W) of the servo driver with the colors
(pin number for cannon plugs) of the motor output cables.
[11] Be sure to connect the earth ground terminal of the motor to the grounding terminal of the servo driver
and ground it together with the ground terminal of the noise filter. Please also ground the machine
body. Grounding resistance should be less than 100 Ω. Tighten the servo driver's ground screw with
the appropriate torque specified for each size. Please use the wire diameter of the ground wire be equal
to or larger than the wire diameter specified in the each model specification. Also, please avoid direct
contact between aluminum and copper to avoid the effect of electrolytic corrosion.
[12] Attach the serge absorbing circuits for preventing noises to an electromagnetic contactor placed
around the servo driver, a coil between relay contact points, and a brake winding of motor with a
brake.
[13] Attach the no fuse breaker (MCCB). In case of emergency, make sure to power off outside the servo
driver. To use an earth leakage circuit breaker, use that in which a high frequency wave
countermeasure is taken.
[14] In order to reduce the terminal noise voltage, install a noise filter.
[15] Turn ON the power after the wiring was finished.
