SIM ENC
Connecting cable for simulated-encoder signals
When the encoder feedback is to operate at greater than 4096 pulses
per revolution, a suitable connecting cable must be used. Each line pair
must be terminated at the system controller or PLC by a resistor of an
appropriate value.
Analog outputs
The analog outputs (pins 9 and 11) are intended for
indication purposes, not for use in process control.
The signal level on Analog output 2 may become
inaccurate at the following occasions:
During the process of saving parameter values
At power-up and power-down
Any cable connecting to the SIM ENC connector should
have its cable shield connected to Pin 15. Failure to do
so could result in the Drive being damaged.
