List of signals for the digital outputs
Signal
1 = Ready to switch on
1 = Ready to operate (DC link loaded, pulses blocked)
1 = Operation enabled (drive follows n_set)
1 = Fault present
0 = Coast to stop active (OFF2)
0 = Fast stop active (OFF3)
1 = Power-on disable
1 = Alarm present
1 = Speed setpoint/actual deviation in the tolerance bandwidth
(p2163, p2166)
1 = Control required to PLC
1 = f or n comparison value reached or exceeded (p2141, p2142)
1 = I, M, or P limit reached (p0640, p1520, p1521)
Reserved
0 = Alarm motor overtemperature (A7910)
Reserved
0 = Alarm thermal overload in power unit (A5000)
1 = Pulses enabled (inverter is clocking, drive is carrying current)
1 = n_act ≤ p2155
1 = n_act > p2155
1 = Ramp-up/ramp-down completed
1 = n_act < p2161 (preferably as n_min or n=0 message)
1 = Torque setpoint < p2174
1 = LOCAL mode active (control via operator panel)
0 = Motor blocked
1 = Ready to switch on

Monitoring functions and protective functions

The drive features hardware and software functions that protect it against faults and damage
caused by impermissible operating statuses or hardware malfunctions. The monitoring
elements provide internal microprocessor-controlled monitoring and remote device monitoring.
