Capacityyofyprotectionydevicesy(suchyasycircuityprotectors)
When a motor is stopped suddenly, a large half-wave rectified current flows
through the motor for 0.2 to 0.4 seconds. When connecting a protective device
such as a circuit protector to the motor, refer to the table below for the braking
current and select its current capacity.

Operation
This section covers the methods of operating and (instantaneously) stopping a
motor using the brake pack.
„
„
Induction„motor,„reversible„motor
Start/instantaneousystop
• Set the brake release input to "OFF."
• Turning CW operation input to "ON" will operate the motor in the CW
direction, while turning it to "OFF" will trigger an instantaneous stop.
• Turning CCW operation input to "ON" will operate the motor in the CCW
direction, while turning it to "OFF" will trigger an instantaneous stop. This
function is not applicable to an induction motor which has four lead wires.
Start/stop
• Set the brake release input to "ON."
• Turning CW operation input to "ON" will operate the motor in the CW
direction, while turning it to "OFF" will stop the motor.
• Turning CCW operation input to "ON" will operate the motor in the CCW
direction, while turning it to "OFF" will stop the motor. This function is
not applicable to an induction motor which has four lead wires.
The stopping time varies, depending on its inertial and frictional loads.

Start/instantaneousystopywithytheyelectromagneticybrakeyenabled
• Set the brake release input to "OFF."
• Turning CW operation input to "ON" will "release" the electromagnetic
brake and operate the motor in the CW direction.
Turning it to "OFF" will trigger an instantaneous stop.
The electromagnetic brake will be "activated" in order to hold the load in
position the moment the motor stops.
• Turning CCW operation input to "ON" will "release" the electromagnetic
brake and operate the motor in the CCW direction.
Turning it to "OFF" will trigger an instantaneous stop.
The electromagnetic brake will be "activated" in order to hold the load in
position the moment the motor stops.
Start/stopywithytheyelectromagneticybrakeydisabled
• Set the brake release input to "ON."
• Turning CW operation input to "ON" will operate the motor in the CW
direction, while turning it to "OFF" will stop the motor.
• Turning CCW operation input to "ON" will operate the motor in the CCW
direction, while turning it to "OFF" will stop the motor.
Setting the brake release input to "ON" will "release" the electromagnetic
brake. To move the load of the motor with electromagnetic brake manually,
set the brake-release input to "ON."

1 Do not set the CW operation input, CCW operation input or brake release
input to ON before turning on the AC power.
Setting these inputs to ON before turning on the AC power will not enable
motor operation.
ޓ
An ALARM indicator will light and ALARM output will switch to "OFF."

2 The brake release input serves as the ALARM-RESET input when the
ALARM output is OFF.
