PREPARING FOR USE
9.1
Warnings before starting up
Make sure you have run the electrical connections as described in CAP 8.2 / 8.3 and as indicated
in the operation and maintenance manual of the drive.
Avoid operating the motor outside the values shown on the plate.
WARNING:
Ensure, before putting the motor into service, that the machinery in which it is
incorporated has been declared in compliance with Machinery Directive
2006/42/EC.
9.2
Starting and stopping
-
For starting/stopping operations, follow the instructions in the operation and maintenance
manual.
-
Check that noise, vibration, and supply voltage are correct.
-
For motors equipped with brake read carefully the warnings in the following paragraphs.
PREMISE:
The motors equipped with standard brake provide a spring brake, this is static brakes
with reverse action that the braking force is applied in the absence of tension.
9.3
WARNING FOR MOTOR EQUIPPED WITH PARKING BRAKE
The brakes used on all motors are sized to keep the engine locked and not to perform dynamic
braking, in case you need to use the brake to curb the motor you should contact the technical
office to verify the possibility.
The nominal braking torque indicated on the brake is therefore static.
The safety brake creates an motor temperature increase of about 20°C, so it is necessary or
oversize the engine appropriately if the brake service factor is significant, or after having fed for
2 seconds the brake reduce its voltage to the retention value (see table below), in this way the
heat produced by the brake is reduced by 2/3.
