Shock or strong pressure applied to the motor shaft may damage 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.
If an external brake is installed, applying a holding brake while the motor is running will cause
excessive wear and loss of braking force. Heat will also decrease the braking force.
CAUTION
LOSS OF BRAKING FORCE DUE TO WEAR OR HIGH TEMPERATURE
• Do not use the brake as a service brake.
• “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 injury or equipment damage.
If power outage and interruptions cause the power stage to be switched off, the motor is no
longer stopped by braking force and may increase its speed until it reaches a mechanical stop.
CAUTION
MOTOR WITHOUT BRAKING EFFECT
Determine the mechanical situation. If necessary, use a cushioned mechanical stop or a suitable brake.
Failure to follow these instructions can result in injury or equipment damage.
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.
CAUTION
LOAD FALLS DURING SWITCHING ON
In such applications, limit the load to a maximum of 25% of the static holding torque.
Failure to follow these instructions can result in injury or equipment damage.
