F07435 (N) Drive: Setting the ramp-function generator for encoderless vector control
Reaction: OFF2 (IASC/DCBRAKE, NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: During operation with encoderless vector control (r1407.1) the ramp-function generator was stopped (p1141). An
internal setting command of the ramp-function generator output caused the set setpoint speed to be frozen.
Remedy: - deactivate the holding command for the ramp-function generator (p1141).
- suppress the fault (p2101, p2119). This is necessary if the ramp-function generator is held using jogging and the
speed setpoint is simultaneously inhibited (r0898.6).
F07436 (A) Free technology controller 0 actual value limited
Reaction: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The actual signal of the free technology controller 0 has reached its limit.
- Fault value = 1: upper limit reached
- Fault value = 2: lower limit reached
Remedy: - Adapt the limits in P11067, P11068 to the signal level.
- Check scaling of the actual signal.
See also: p11067 (Free tec_ctrl 0 actual value upper limit), p11068 (Free tec_ctrl 0 actual value lower limit)
F07437 (A) Free technology controller 1 actual value limited
Reaction: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The actual signal of the free technology controller 1 has reached its limit.
- Fault value = 1: upper limit reached
- Fault value = 2: lower limit reached
Remedy: - Adapt the limits in P11067, P11068 to the signal level.
- Check scaling of the actual signal.
See also: p11167 (Free tec_ctrl 1 actual value upper limit), p11168 (Free tec_ctrl 1 actual value lower limit)
F07438 (A) Free technology controller 2 actual value limited
Reaction: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The actual signal of the free technology controller 2 has reached its limit.
- Fault value = 1: upper limit reached
- Fault value = 2: lower limit reached
Remedy: - Adapt the limits in P11267, P11268 to the signal level.
- Check scaling of the actual signal.
See also: p11267 (Free tec_ctrl 2 actual value upper limit), p11268 (Free tec_ctrl 2 actual value lower limit)
A07530 Drive: Drive Data Set DDS not present
Reaction: NONE
Acknowledge: NONE
Cause: The selected drive data set is not available (p0837 > p0180). The drive data set was not changed over.
See also: p0180 (Number of Drive Data Sets (DDS)), p0820 (Drive Data Set selection DDS bit 0), p0821 (Drive Data
Set selection DDS bit 1), r0837 (Drive Data Set DDS selected)
Remedy: - select the existing drive data set.
- set up additional drive data sets.
