Cautions Concerning Use

Cautions concerning model selection
• Select a motor with a rated torque above the continuous
effective load torque.
• Design the operation pattern in the command section so that
positioning can be completed, taking the stop setting time
(ts) into account .
• The load inertia moment should be below the recommend-
ed load inertia moment ratio of the motor being used. If it is
too large, desired performance may not be attainable.
Operation
• When a magnetic contactor (MC) is installed on the amplifi-
er’s primary side, do not perform frequent starts and stops
with the MC. Doing so could cause the amplifier to fail.
• As for 7kW or smaller, when a trouble occurs, the amplifier’s
safety features are activated, halting output, and the dynam-
ic brake instantly stops the motor. If free run is required, con-
tact Mitsubishi about solutions involving servo amplifiers
where the dynamic brake is not activated.
• When an error occurs, the 11kW or larger amplifier’s protec-
tion function will activate and the output will stop. The servo
motor will coast to a stop. If the dynamic brake operation is
required, use the option DBU-MK(-4).
• When using a motor with an electromagnetic brake, do not
apply the brake when the servo is on. Doing so could cause
an amplifier overload or shorten brake life. Apply the brake
when the servo is off.
