Status word 1 (ZSW1)
Bit
Meaning
Remarks
Signal inter-
connection in
the inverter
0 1 = Ready to start Power supply switched on; electronics ini-
tialized; 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. Acknowledge fault
using STW1.7.
p2080[3] =
r2139.3
4 1 = OFF2 inactive Coast down to standstill is not active. p2080[4] =
r0899.4
5 1 = OFF3 inactive Quick stop is not active. p2080[5] =
r0899.5
6 1 = Switch-on inhibit 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 acknowl-
edgement is necessary.
p2080[7] =
r2139.7
8 1 = Speed deviation within the
tolerance range
Setpoint / actual value deviation within the
tolerance range.
p2080[8] =
r2197.7
9 1 = Master control requested The automation system is requested to
accept the inverter control.
p2080[9] =
r0899.9

1 = Comparison speed reached or
exceeded
Speed is greater than or equal to the corre-
sponding maximum speed.
p2080[10] =
r2199.1
11 1 = Torque limit not reached Comparison value for current or torque has
been fallen below.
p2080[11] =
r0056.13 /
r1407.7

r0899.12
13 0 = Alarm, motor overtemperature -- p2080[13] =
r2135.14

1 = Motor rotates clockwise
Internal inverter actual value > 0
p2080[14] =
r2197.3
0 = Motor rotates counterclock-
wise
Internal inverter actual value < 0
15 0 = Alarm, inverter thermal over-
load
