IMPULSE®•G+ & VG+ Series 4 Instruction Manual – February 2017
6-12
PULSDEV
Pulse Deviation
Pulse Deviation.
The pulse input
into terminal RP compared to the
pulse output from terminal MP is
greater than the percentage
programmed into H06-09.
1. During operation, verify that there
is an incoming pulse signal on
the RP terminal, viewable at U01-
54.
2. Increase the deviation margin
percentage in parameter H06-09.
X
RF
Braking Resistor Fault.
the
resistance of the braking resistor is
too low, or the proper braking resistor
has not been installed.
1. Verify correct braking resistor.
X
RH
Braking Resistor Overheat.
Deceleration time is too short and
excessive regenerative energy is
flowing back into the drive.
1. Verify correct braking resistor.
X
RR
DynBrk Transistr
Braking Transistor Fault.
Internal
Braking transistor failed.
1. Verify that the external braking
resistor is connected to the
proper terminals.
2. Confirm that the proper resistor is
installed.
3. Check for a short circuit across
the braking resistor.
X
SC
Short Circuit
Short Circuit Fault.
The inverter has
detected an output short circuit
condition.
1. Disconnect the motor from the
inverter.
2. Check for a short circuit in the
motor or wiring using a megger.
X
SLC
Slack Cable
Detection
Slack Cable Fault.
A hoist slack
cable condition occurred.
1. May not require corrective action.
2. Check proper programming of
Slack Cable Detection (C11-xx).
X
SNAP
Snapped Shaft
Snapped Shaft Fault.
A drive train
discontinuity has been detected.
Alarm or fault defined by C11-09.
1. Check for loose or broken
coupling.
2. Check for loose encoder(s).
3. Check for broken shaft.
X
X
TST END
Exit Test Mode
Exceeded the 10 minute time limit.
1. Ensure the test mode MFDI is
OFF.
2. Reset the fault (Fault Reset
MFDI, Keypad, or cycle power)
3. Ensure that test mode is not used
for normal operation.
X
UBNC
Unbalanced Cur
Current Unbalance.
Current flow
has become unbalanced.
Exclusive to 4810 and 41090 models.
1. Check wiring.
2. Check for damaged transistors.
3. Check for short circuits or
grounding problems on the
connected motor.
X
UL1
Upper Limit 1 Err
Upper Limit 1—SLOW DOWN
Indicator.
Upper Limit 1—SLOW
DOWN switch status is changed.
1. May not require corrective action.
2. Check the limit switches location.
3. Check the limit switches
condition.
X
UL2
Upper Limit 2 Err
Upper Limit 2—STOP Indicator.
Upper Limit 2—STOP switch status
is changed.
1. May not require corrective action.
2. Check the limit switches location.
3. Check the limit switches
condition.
