Bit Meaning
Remarks
Signal inter‐
connection in
the inverter
0
1 = Ready for switching on
Power supply switched on; electronics 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. Acknowledge fault using
STW1.7.
p2080[3] =
r2139.3

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 acknowledge‐
ment is necessary.
p2080[7] =
r2139.7
8
1 = Speed deviation within the
tolerance range

ance range.
p2080[8] =
r2197.7
9
1 = Master control requested
The automation system is requested to accept
the inverter control.
p2080[9] =
r0899.9
10 1 = Comparison speed
reached or exceeded
Speed is greater than or equal to the correspond‐
ing maximum speed.
p2080[10] =
r2199.1
11 1 = Torque limit not reached
Comparison value for current or torque has been
fallen below.
p2080[11] =

12 Reserved
p2080[12] =
r0899.12
13 0 = Alarm, motor overtempera‐
ture
--
p2080[13] =
r2135.14
14 1 = Motor rotates clockwise
Internal inverter actual value > 0
p2080[14] =
r2197.3
0 = Motor rotates counter-
clockwise
Internal inverter actual value < 0
15 0 = Alarm, inverter thermal
overload
