FAILURE
POSSIBLE CAUSES
The speed during acceleration with max. current is not linear
Reduce the Speed I and Speed P proportionally. If this does not lead to an improvement,
optimize the regulator (see chapter 5.3.6).
Speed oscillating
Check Speed P and Speed I parameter
If the operating point is in the field weak range, check the Fld reg P gain and Fld
reg I gain parameters and eventually Voltage P and Voltage I parameters.
Remedy: Optimize the regulator as previously described
Drive not reacting to adaptive speed regulation
Adaptive speed regulation not enabled. Enable spd adap = Enabled
Motor potentiometer function not executed
Function not enabled. Enable motor pot = Enabled
With operation via the terminal strip: Motor pot up and/or Motor pot down were not
assigned to a digital input
Jog operation not possible
A start command is still present
Function not enabled. Enable jog = Enabled
With operation via terminal strip: Jog + and/or Jog - were not assigned to a digital input.
Internal speed reference values not carried out
Function not enabled. Enab multi spd = Enabled
With operation via terminal strip: Speed sel 0, Speed sel 1 and Speed sel 2 were not
assigned to a digital input.
Multi-Ramp function not reacting
Function not enabled. Enab multi rmp = Enabled
With operation via terminal strip: Ramp sel 0 and Ramp sel 1 were not assigned to a
digital input
Overload not possible
Function not enabled. Enable overload = Enabled
