corrective action
Additional information and descriptions in
the manual
Let the motor cool down.
Check the motor encoder cable.
Check the entry in the motor table.
Measure the temperature sensor.
See "Speed Encoders" on page 18 – 293.
See Service Manual Inverter Systems and
Motors.
Check the software version.
Operate the motor at another encoder input.
Exchange drive control board.
Check the control and cabling of the pulse
release.
Check Uz.
If the power supply is not regenerative: Is
the braking resistor connected?
If the power supply is regenerative: Is the
energy recovery activated?
Check the grounding and shielding of the
cable.
Exchange the power module.
For P controls: Exchange the interface card
Exchange the motor drive control board.
See "Checking the Enables on the iTNC
530" on page 16 – 229.
See Service Manual Inverter Systems and
Motors.
Check the motor encoder and leads.
Exchange the motor control board.
See "Speed Encoders" on page 18 – 293.
Check the motor cabling.
Check motor and motor encoder cabling.
Check motor table entry.
Check I2t monitoring (MP2302.x).
See "Speed Encoders" on page 18 – 293.
See Service Manual Inverter Systems and
Motors.
Exchange the motor drive control board.
Check the software version.
