Test
See startup guide for voltage checks.
See open fuses and tripped circuit
breaker in this section for possible
causes.
Perform pre-startup check for loose
connections.
Missing customer connections can cause
the safety circuit or start signal to be
open.
Check all customer connections for
tightness. Loose customer connections
can act like an open circuit.
make sure wires are connected to correct
terminals.
See pre-startup check list.
See pre-startup check list to see if motor
and power leads were swapped.
Verify that the disconnect or circuit
breaker is closed.
Verify that operator devices are in
operating position per startup
procedures.
A tripped OL will disable the motor from
running. Verify that OL relay is in the
normal operating position per the
manual.
See pre-startup check list and correct
improper voltages.
Motor and line voltages swapped. Make
sure the line in and motor out are on
the correct terminals. See pre-startup
check list.
Check motor and panel power wires to
ground.
Motor or panel has a short phase to
phase. Check motor and panel phase to
phase for shorts.
Motor is overloaded for the application.
Drive is overloaded for the application.
Perform pre-startup check for loose
connections.
Solution
Correct voltage at source.
Reset circuit breaker. If fuses, check for
opens with power removed from panel.
Tighten loose connections in the panel.
See customer connections and make
sure all applicable connections are
made or jumpers installed, especially
customer interlock.
Tighten loose customer connections.
Correct any wrong connections. This
could potentially cause damage to the
panel.
Correct the voltage mismatch. This
could potentially damage the panel.
Use caution when applying power.
Correct any wrong connections. This
could potentially cause damage to the
panel.
Correct any wrong connections. This
could potentially cause damage to the
panel.
Set switches to the correct position.
Perform pre-startup checklist and set
OL per instructions.
Correct voltage mismatch. This could
potentially damage the panel. Use
caution when applying power.
Correct any wrong connections. This
could potentially cause damage to the
panel.
Eliminate any ground faults detected.
Eliminate any shorts detected.
Perform startup and verify motor
current is within specifications. If motor
current is exceeding nameplate FLA,
reduce the load on the motor.
Perform startup and verify that drive
current is within specifications. If not,
reduce the load on the motor.
Tighten loose connections.
