12 Reserved
13 1 = MOP up Increase the setpoint saved in the motorized potenti‐
ometer.
p1035[0] =

Bit Meaning Remarks Signal intercon‐
nection in the
converter
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 converter switches on
the motor.
p2080[1] =
r0899.1
2 1 = Operation enabled Motor follows setpoint. See control word1, bit3. p2080[2] =
r0899.2
3 1 = Fault active The converter 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 = Switching on inhibited ac‐
tive
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 acknowledgement 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 converter con‐
trol.
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 torque has been fallen below. p2080[11] =
r0056.13 /
r1407.7
12 Reserved p2080[12] =
r0899.12
13 0 = Alarm, motor overtemper‐
ature
-- p2080[13] =
