User's manual
DESCRIPTION
Undervoltage may occur when the mains transformer is not
powerful enough to sustain the loads or when powerful motors
are started up on the same line.
Try to stabilise the line by taking appropriate measures. If
necessary, enable the BUS support function for mains failure
(C34=1). This however can only help motors with light loads.
Try to understand why main supply is lost.
The safety switch cuts in mainly due to excessively short
braking times. The best solution is to lengthen the braking
times.
An overvoltage in the mains may also trigger the safety switch.
If the drive is fitted with a braking circuit, check that the
resistance value is not too high to absorb the peak power.
If the resistor is not too hot, check the resistor and connection
continuity and ensure that the circuit functions correctly.
Check and enable connection C29 "Drive software enable"
Check why the Power Soft start isn't enabled
Check the radiator temperature (d25)
Please contact TDEMacno assistance
Check the voltage of the three input phases.
Try switching off and then back on, measuring the DC Bus level
(with the monitor or tester).
If the problem repeats, contact TDE as there must be a soft
start circuit malfunction.
Bring +24V to connectors S1 and S3.
If the user want to use the Safe Torque Off function without
alarms, it's necessary to set C73=1.
Swap over two phases and repeat the connection tests.
Check motor phases
Number of motor poles (P67) set incorrectly or more sensor
poles (P68) than motor poles have been set.
Number of revolutions per pulse selected (C51) is not
compatible with the maximum speed (P65). See "Feedback
Option" enclosure.
