Internal customer unit (internal data bus) faulty or damaged
by radio radiation (EMC)
• Check control connections for short circuit.
• Minimize EMC interference by laying control and power
cables separately.
• Device and shielding must be well grounded.
The Watchdog function is selected at a digital input and the
impulse at the corresponding digital input is not present for
longer than the time set in parameter P460 >Watchdog
time<.
• Check connections
• Check setting P460
The drive switch-off limit (P534 [-01]) has triggered.
• Reduce load on motor
• Set higher value in (P534 [-01]).
The generator switch-off limit (P534 [-02]) has triggered.
• Reduce load on motor
• Set higher value in (P534 [-02]).
Limit from potentiometer or setpoint source has switched off.
P400 = 12
Limit from potentiometer or setpoint source has switched off.
P400 = 14
Switch-off due to overshooting or undershooting of
permissible load torques ((P525) ... (P529)) for the time set
in (P528).
• Adjust load
• Change limit values ((P525) ... (P527))
• Increase delay time (P528)
• Change monitoring mode (P529)
Switch-off due to undershooting of the 0% adjustment value
(P402) with setting (P401) "0-10 V with switch-off on error 1"
or "....2"
Switch-off due to overshooting of the 100% adjustment
value (P402) with setting (P401) "0-10 V with switch-off on
error 1" or "....2"
