Status word 1 (ZSW1), PZD send word 1 (word: p2051[0], bits: p2080[0] … p2080[15])
Power supply switched on; electronics initialized; pulses locked.
1 1 = Ready Motor is switched on (ON/OFF1 = 1), no fault is active. With the command "Enable
operation" (STW1.3), the inverter switches on the motor.
Motor follows setpoint. See control word 1, bit 3.
3 1 = Fault active The inverter has a fault. Acknowledge fault using STW1.7.
Coast down to standstill is not active.
Quick stop is not active.
1 = Closing lockout active
It is only possible to switch on the motor after an OFF1 followed by ON.
Motor remains switched on; no acknowledgement is necessary.
8 1 = Speed deviation within the
Setpoint / actual value deviation within the tolerance range.
1 = Master control requested
The automation system is requested to accept the inverter control.
10 1 = Comparison speed reached
Speed is greater than or equal to the corresponding maximum speed.
Comparison value for current or torque has been reached or exceeded.
Signal to open and close a motor holding brake.
13 0 = Alarm, motor overtempera-
1 = Motor rotates clockwise
Internal inverter actual value > 0
0 = Motor rotates counter-
Internal inverter actual value < 0
