Status word 1 (ZSW1), PZD send word 1 (word: p2051[0], bits: p2080[0] … p2080[15])
Bit
Meaning
Comments
0
1 = Ready to start
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.
2
1 = Operation enabled
Motor follows setpoint. See control word 1, bit 3.
3 1 = Fault active The inverter has a fault. Acknowledge fault using STW1.7.
4
1 = OFF2 inactive
Coast down to standstill is not active.
5
1 = OFF3 inactive
Quick stop is not active.
6
1 = Closing lockout active
It is only possible to switch on the motor after an OFF1 followed by ON.
7
1 = Alarm active
Motor remains switched on; no acknowledgement is necessary.
8 1 = Speed deviation within the
tolerance range
Setpoint / actual value deviation within the tolerance range.
9
1 = Master control requested
The automation system is requested to accept the inverter control.
10 1 = Comparison speed reached
or exceeded
Speed is greater than or equal to the corresponding maximum speed.
11
1 = torque limit reached
Comparison value for current or torque has been reached or exceeded.
12
1 = Holding brake open
Signal to open and close a motor holding brake.
13 0 = Alarm, motor overtempera-
ture
--
14
1 = Motor rotates clockwise
Internal inverter actual value > 0
0 = Motor rotates counter-
clockwise
Internal inverter actual value < 0
15 0 = Alarm, inverter thermal
overload
Fault word according to the VIK-NAMUR definition (MELD_NAMUR), PZD send word 16 (word:
p2051[5], bits: r3113.00 … r3113.15)
Bit
Meaning
0
0 = Control Unit has a no fault
1 = Control Unit fault
1
1 = line fault: Phase failure or inadmissible voltage
2
1 = DC link overvoltage
3
1 = Power Module fault, e.g. overcurrent or overtemperature
4
1 = inverter overtemperature
5
1 = ground fault/phase fault in the motor cable or in the motor
6
1 = motor overload
7
1 = communication error to the higher-level control
8
1 = error in a safe monitoring channel
10
1 = internal communication error in the inverter
11
1 = line fault
15
1 = other fault
