MOTOR WITHOUT BRAKING EFFECT<br />
<strong>MDrive</strong>Plus <strong>EtherNet</strong>/<strong>IP</strong><br />
If power outage and faults cause the power stage to be switched<br />
off, the motor is no longer stopped by the brake and may increase<br />
its speed even more until it reaches a mechanical stop.<br />
• Verify the mechanical situation.<br />
• If necessary, use a cushioned mechanical stop or a suitable<br />
brake.<br />
Failure to follow these instructions can result in death or<br />
serious injury.<br />
LOSS OF BRAKING FORCE DUE TO WEAR OR HIGH TEMPERATURE<br />
Applying the holding brake while the motor is running will cause<br />
excessive wear and loss of the braking force. Heat decreases the<br />
braking force.<br />
• Do not use the brake as a service brake.<br />
• Note that “EMERGENCY STOPS” may also cause wear<br />
• At operating temperatures of more than 80°C (176°F), do not<br />
exceed a maximum of 50% of the specifi ed holding torque<br />
when using the brake.<br />
Failure to follow these instructions can result in death or<br />
serious injury.<br />
LOAD FALLS DURING SWITCHING ON<br />
When the brake of stepping motor drives is released and external<br />
forces are applied (vertical axes), the load may fall if the friction is<br />
low.<br />
• In such applications, limit the load to a maximum of 25% of<br />
the static holding torque.<br />
Failure to follow these instructions can result in death or<br />
serious injury.<br />
To install a drive in locations difficult to access, it may be useful to carry<br />
out the electrical installation first and then install the fully wired drive.<br />
