Status word 1 (ZSW1)
Bit Meaning Remarks Signal interconnection
in the inverter
0 1 = Ready to start Power supply switched on; electron‐
ics initialized; pulses locked.
p2080[0] = r0899.0
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.
p2080[1] = r0899.1
2 1 = Operation enabled Motor follows setpoint. See control
word 1, bit 3.
p2080[2] = r0899.2
3 1 = Fault active The inverter has a fault. Acknowl‐
edge fault using STW1.7.
p2080[3] = r2139.3
4 1 = OFF2 inactive Coast down to standstill is not ac‐
tive.
p2080[4] = r0899.4
5 1 = OFF3 inactive Quick stop is not active. p2080[5] = r0899.5
6 1 = Closing lockout active It is only possible to switch on the
motor after an OFF1 followed by
ON.
p2080[6] = r0899.6
7 1 = Alarm active Motor remains switched on; no ac‐
knowledgement is necessary.
p2080[7] = r2139.7
8 1 = Speed deviation within the tol‐
erance range
Setpoint / actual value deviation
within the tolerance range.
p2080[8] = r2197.7
9 1 = Master control requested The automation system is reques‐
ted to accept the inverter control.
p2080[9] = r0899.9
10 1 = Comparison speed reached or
exceeded
Speed is greater than or equal to
the corresponding maximum speed.
p2080[10] = r2199.1
11 1 = Torque limit not reached Comparison value for current or tor‐
que has been fallen below.
p2080[11] = r0056.13 /
r1407.7
12 Reserved p2080[12] = r0899.12
13 0 = Alarm, motor overtemperature -- p2080[13] = r2135.14
14 1 = Motor rotates clockwise Internal inverter actual value > 0 p2080[14] = r2197.3
0 = Motor rotates counterclockwise Internal inverter actual value < 0
15 0 = Alarm, inverter thermal over‐
load
p2080[15] = r2135.15
