Description
Selects whether measured motor 1 temperature is used in the motor
model compensation.
The function is inactive.
The temperature is used in the motor model compensation.
Note: Selection is possible only when Pt100 sensor(s) are used.
Encoder connection. Visible only when a pulse encoder module
(optional) is installed and activated by
The settings will remain the same even though the application macro
is changed.
States the number of encoder pulses per one revolution.
Pulse number in pulses per round (ppr)
Defines how the encoder pulses are calculated.
Channel A: positive edges calculated for speed. Channel B: direction. 1
Channel A: positive and negative edges calculated for speed. Channel
B: not used.
Channel A: positive and negative edges are calculated for speed.
Channel B: direction.
All edges of the signals are calculated.(Recommended Setting)
Defines the operation of the drive if a failure is detected in
communication between the pulse encoder and the Pulse Encoder
Interface Module or in between the module and the drive. Encoder
supervision function activates if either of the following conditions is
valid:
- There is a 20% difference between the estimated speed and the
measured speed received from the encoder.
- No pulses are received from the encoder within the defined time
(see 50.04 ENCODER DELAY) and the motor torque is at the
allowed maximum value.
The drive generates a warning indication.
The drive trips on a fault, gives a fault indication and stops the motor.
Defines the time delay for the encoder supervision function (See
ENCODER FAULT).
Time delay
Defines the fiber optic channel of the control board from which the
drive program reads the signals coming from the Pulse Encoder
Interface Module. The setting is valid only if the module is connected
to the drive via the DDCS link (i.e. not to the option slot of the drive).
Signals via Channel 1 (CH1). The Pulse Encoder Module must be
connected to CH1 instead of CH2 in applications where CH2 is
reserved by a Master Station (e.g. a Master / Follower application).
Signals via Channel 2 (CH2). Can be used in most cases.
Defines how the encoder pulses are calculated.
Calculated speed estimate.
Actual speed measured with an encoder.
Medium filter time for the speed measurement in the NTAC module.
