Main circuit overheat
The temperature inside the driver exceeded the
overheat warning level.
Reconsider the ventilation condition in the
enclosure.
Undervoltage
*
The main power supply voltage dropped by
approximately 10% or more from the rated voltage.
•
Check the input voltage of the main power
supply.
•
Check the wiring of the power supply cable.
Overload
*
The load torque of the motor exceeded the overload
warning level.
•
Decrease the load.
•
Reconsider the operating condition such as
acceleration time and deceleration time.
Operation prohibited
•
When moved from the test mode to other mode
using the
MEXE02
or
OPX-2A
, the FWD input or
REV input was being ON.
•
When the assignment of the input terminal was
changed using the
MEXE02
or
OPX-2A
, the
assigned terminal was ON.
Turn the input signal OFF.

Using a controller with a built-in clamp diode
If a controller with a built-in clamp diode is used, a leakage
path may form and cause the motor to operate even when the
controller power is o, as long as the driver power is on. Since
the power capacity of the controller is dierent from that of the
driver, the motor may operate when the controller and driver
powers are turned on or o simultaneously.
When powering down, turn o the driver power rst, followed
by the controller power, and when powering up, turn on the
controller power rst, followed by the driver power.
