Troubleshooting
Power Loss
3
➀
Drive has sensed a power line loss.
Precharge
Active
1
➀
Drive is in the initial DC bus precharge state.
Prof Step
Cflct
50
➁
An error is detected in trend step(s).
•
Set if Sleep Mode is enabled.
•
Set if:
any profile step uses “Encoder Incr” and/or “Enc Absolute”
and
[Motor Cntl Sel], parameter 53 is not set to “FVC Vector”
and
[Feedback Select], parameter 80 is not set to “Encoder” or “Simulator”
and
[Speed/Torque Mod], parameter 88 = “7” (Pos/Spd Prof).
•
a Step Type is configured for “Dig Input” and the Step Value is greater
than 6, less than –6, or zero
or
the digital input selected with [Digital Inx Sel] is not set to “57, Prof Input.”
•
Cleared if none of the above occur.
PTC Conflict
31
➁
PTC is enabled for Analog In 1, which is configured as a 0-20 mA current
source in [Anlg In Config].
Sleep Config 29
➁
Sleep/Wake configuration error. With [Sleep-Wake Mode] = “Direct,” possible
causes include: drive is stopped and [Wake Level] < [Sleep Level].“Stop=CF,”
“Run,” “Run Forward,” or “Run Reverse.” is not configured in [Digital Inx Sel].
Speed Ref
Cflct
27
➁
[Speed Ref x Sel] or [PI Reference Sel] is set to “Reserved”.
Start At
PowerUp
4
➀
[Start At PowerUp] is enabled. Drive may start at any time within 10 seconds
of drive powerup.
TB Man Ref
Cflct
30
➁
Occurs when:
•
“Auto/Manual” is selected (default) for [Digital In3 Sel], parameter 363
and
•
[TB Man Ref Sel], parameter 96 has been reprogrammed.
No other use for the selected analog input may be programmed.
Example: If [TB Man Ref Sel] is reprogrammed to “Analog In 2,” all of the
factory default uses for “Analog In 2” must be reprogramed (such as
parameters 90, 117, 128 and 179). See also
To correct:
•
Verify/reprogram the parameters that reference an analog input
or
•
Reprogram [Digital In3] to another function or “Unused.”
TorqProve
Cflct
49
➁
When [TorqProve Cnfg] is enabled, [Motor Cntl Sel], [Feedback Select] and
[Motor Fdbk Type] must be properly set (refer to
).
UnderVoltage 2
➀
The bus voltage has dropped below a predetermined value.
VHz Neg Slope 24
➁
[Torq Perf Mode] = “Custom V/Hz” & the V/Hz slope is negative.
Waking
11
➀
The Wake timer is counting toward a value that will start the drive.
