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.
• When a trouble occurs, the amplifier’s safety features are
activated, halting output, and the dynamic brake instantly
stops the motor. If free run is required, contact Mitsubishi
about solutions involving servo amplifiers where the dynam-
ic brake is not activated.
• 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.
