Mechanical Installation
Shock or strong pressure applied to the motor shaft may destroy the motor.
CAUTION
MOTOR DAMAGE AND LOSS OF CONTROL
• Protect the motor shaft during handling and transportation.
• Avoid shocks to the motor shaft during mounting.
• Do not press parts onto the shaft. Mount parts to the shaft by gluing, clamping, shrink-fitting, or
screwing.
Failure to follow these instructions can result in injury or equipment damage.
WARNING
MOTOR WITHOUT BRAKING EFFECT
If power outage and faults cause the power stage to be switched off, the motor is no longer stopped by
the brake and may increase its speed even more until it reaches a mechanical stop.
• Verify the mechanical situation.
• If necessary, use a cushioned mechanical stop or a suitable brake.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
WARNING
LOSS OF BRAKING FORCE DUE TO WEAR OR HIGH TEMPERATURE
Applying the holding brake while the motor is running will cause excessive wear and loss of the braking
force. Heat decreases the braking force.
• Do not use the brake as a service brake.
• Note that “EMERGENCY STOPS” may also cause wear
• At operating temperatures of more than 80°C (176°F), do not exceed a maximum of 50% of the
specified holding torque when using the brake.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
WARNING
LOAD FALLS DURING SWITCHING ON
When the brake of stepping motor drives is released and external forces are applied (vertical axes), the
load may fall if the friction is low.
• In such applications, limit the load to a maximum of 25% of the static holding torque.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
