Troubleshooting
Clearing Alarms
Alarms are automatically cleared when the condition that caused the alarm is no
longer present.
Alarm Descriptions
The status of the alarms can be viewed in
[Drive Alarm 1].
Table 42 - Alarm Descriptions and Actions
Alarm
Type
Description
Arm Overvoltage 1
There is a possible overvoltage on the armature circuit or Par
[Rated Motor Volt] is set too
low for the application. See the “Arm Overvoltage” fault description on
for more
information.
Auxiliary Input
1
An auxiliary input interlock is open or a voltage (+15 - 30 V) or reference signal is missing for
the digital input set to 14 “Aux Fault”. See the “Auxiliary Input” fault description on
for more information.
BipolarCflct
2
[Direction Mode] is set to “Bipolar” or “Reverse Dis” and one or more of the
following digital input functions is configured: “Fwd/Reverse,” “Run Forward,” “Run
Reverse,” “Jog Forward,” “Jog Reverse,” “Rev Dec Limit,” or “Rev End Limit.”
BrakeSlipped
1
The encoder movement has exceeded the level in Par
[Brk Slip Count] after the brake
was set and the brake slip maneuver is controlling the drive (drive is active).
Cycle power to the drive to reset.
2
The encoder movement has exceeded the level in Par
[Brk Slip Count] after the brake
was set and the brake slip maneuver is finished (drive is stopped).
Cycle power to the drive to reset.
CntactrCflct
2
Contactor input functions are in conflict:
• When Par
[ContactorControl] is set to “None”, both relay outputs (Pars
Out 1 Sel] and
[Relay Out 2 Sel] and all digital inputs ([Digital Inx Sel]) cannot be set
to “Contactor” or “ContactorDB”.
• With [ContactorControl] set to “AC Cntcr” or “DC Cntcr”, one relay output and one digital
input must be set to “Contactor”. No relay or digital output can be defined as
“ContactorDB”.
• With [ContactorControl] set to “AC Cntcr+DB” or “DC Cntcr+DB”, both relay outputs and
one digital input must be set to “Contactor”, “ContactorDB” and “Contactor”, respectively.
Because any relay output can be configured as contactor or DB control and any digital input
as contactor status, care must be taken to correctly wire the terminal blocks to match the
parameter selections.
