CAUTION:
- CHECK THAT THE DRIVE USED ARE CE MARKED OR EQUIVALENT.
- MAKE SURE THE CONNECTIONS AND THE ELECTRICAL SOCKETS ARE PROTECTED FROM FLOODING AND
MOISTURE.
- FOR CONNECTIONS BETWEEN THE MOTOR AND ITS ACCESSORIES, USE APPROPRIATE DIMENSION
CABLES, EQUIPPED WITH SHIELDING AND EARTH CONDUCTOR.
- NON OBSERVANCE OF THESE PROVISIONS MAY CAUSE SIGNIFICANT DAMAGE TO THE SERVOMOTOR.
10 PREPARING FOR USE
10.1 INSTRUCTIONS BEFORE STARTING
- Make sure the electrical wiring has been done as described in CHAP.9.2 / 9.3 and according to the drive using manual
too.
-
Don’t use the motor out of the rated performance showed on its plate.
CAUTION:
- BEFORE THE MOTOR START UP, MAKE SURE THE MACHINE HAS BEEN MANUFACTURED IN CONFORMITY
WITH THE MACHINE DIRECTIVE 2006/42/EC.
10.2 START AND STOP
- For start and stop, keep to the provisions given in the use and maintenance manual of the facility.
- Check that noise, vibration, and power supply voltage are correct.
- In the event of operating trouble, see the TROUBLESHOOTING CHAP. 11.
- In case of motors equipped with brake please read carefully the instructions showed in to the following chapters.
INTRODUCTION
: The motors equipped with brake allows:
A Spring operated brakes for d.c. motors and a Permanent magnet brake or spring operated brakes for the brushless
motors
. In both cases it’s a negative brake. It means the brake action is made when the voltage supply is off.
10.3 WARNING FOR THE MOTORS EQUIPPED WITH PARKING BRAKE
The parking brakes are calculated for a parking motor action and not for dynamic brakes. In case of dynamic braking
needs please contact the TEM technical dept.
The nominal braking torque is a static value.
10.4
WARNING FOR THE BRUSHLESS MOTORS EQUIPPED WITH BRAKE
To get the braking nominal torque the brake needs few cycles. Avoid problems during the first period don’t use the motor
up to its limit because the braking torque will be lesser than the nominal value, for more info request the TKU at TEM.
The safety brake increases the motor temperature of 20°C roughly
. In case of high braking service factor it’s necessary to
over size the motor, or to decrease the brake supply after 2sec. using (see the following table). By the way the overheating
caused by the brake use is 2/3 reduced.

CAUTION:
- START THE MOTOR AFTER CLOSING THE TERMINAL BOX PROPERLY.
- WHEN STARTING THE MOTOR BE SURE YOU ARE NOT BAREFOOT AND/OR IN WATER, OR HAVE WET
HANDS.
11 MOTOR MAINTENANCE AND REPAIRING
11.1 MOTOR CLEANING
The motor
doesn’t require particular cleaning. To allow the motor to disperse the heat produced in the best way possible
you are merely advised to remove the dust and/or encrustation that may be occurred on the stator periodically.
CAUTION:
- DURING OPERATION, THE STATOR CAN REACH A TEMPERATURE CLOSE TO 90°C THEREFORE WAIT FOR IT
TO COOL BEFORE CARRYING OUT ANY MANUAL OPERATIONS.
