Select relay functions/signals

The select relay terminals A11 to A61 (max. 6) can be freely programmed.
A control parameter is assigned to every select relay, in which the code number
of the selected function is entered.
Select relay functions/signals
The relay pulls–in, if the ramp–up sequence has been completed after a setpoint step.
The signal is not withdrawn as a result of speed fluctuations due to load surges.
The relay pulls–in, if the actual value lies within a tolerance bandwidth of the setpoint.
Speed fluctuations due to load surges can cause the signal to be withdrawn.
The relay pulls–in, if the actual torque of the threshold, which can be parameterized, is
fallen below (this is suppressed during acceleration" after a time which can be para-
meterized).
1) The relay pulls–in, if the speed actual value falls below the threshold which can be para-
meterized.
The relay pulls–in, if the speed actual value falls below the threshold which can be para-
meterized.
The relay drops out for an overtemperature condition. If the temperature continues to
1) increase, an additional fault signal is output and the pulses cancelled after a para-
meterizable time.
The relay drops out, if the main heatsink temperature switch of the power module
1) responds. After 20 s the drive shuts down and a fault signal is output.
Any of the control program variables can be monitored using this function.
1)
The relay pulls–in, if the spindle is within tolerance bandwidth 1 after positioning has been
completed.
The relay pulls–in, if the spindle is within tolerance bandwidth 2 after positioning has been
completed.
An external auxiliary contactor can be controlled via this relay to changeover the winding
into the star configuration.
An external auxiliary contactor can be controlled via this relay to changeover the winding
into the delta configuration.
