0 1 = Ready to start Power supply switched on; electronics initial‐
ized; pulses locked.
p2080[0] =
r0899.0
1 1 = Ready Motor is switched on (ON/OFF1 = 1), no fault
is active. With the command "Enable opera‐
tion" (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 us‐
ing STW1.7.
p2080[3] =

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 tol‐
erance range
Setpoint / actual value deviation within the tol‐
erance range.
p2080[8] =
r2197.7
9 1 = Master control requested The automation system is requested to accept
the inverter control.
p2080[9] =

exceeded
Speed is greater than or equal to the corre‐
sponding maximum speed.
p2080[10] =

reached
Comparison value for current or torque has
been reached or exceeded.

14 1 = Motor rotates clockwise Internal inverter actual value > 0 p2080[14] =
r2197.3
0 = Motor rotates counterclockwise Internal inverter actual value < 0
15 1 = CDS display 0 = Alarm, inver‐
ter thermal over‐
