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
ÂșC) 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.
