Description

AXIS 1

AXIS 2

Over Current

RMS

Indicates that the I2T model, hard-coded in the

amplifier processor projecting current output over

time, has been violated within the operating current

specification range of the amplifier.

Over Current

Peak

Indicates that an excessive amount of current

(exceeding the specs of the amplifier) has been

detected through the motor leads. This could be due

to a shorted motor lead or a current/voltage surge.

PWM

Over Frequency

Indicates that the PWM frequency has exceeded the

permissible limit. This can occur if the clock settings

are incorrect, or the presence of a bad PWM cable.

IGBT

Over Temperature

Indicates excessive IGBT temperature (close to 75

ºC) has been detected. Power off the drive and let it

cool down.

Check cabinet ventilation, and fan functionality.

Check for blocked airflow.

Motor

Thermal Relay

Indicates that the normally closed Motor Thermal

contact (connector X3) is in open circuit.
