3. Remove the pressure spring from each brush.
4. Loosen the screw of each wire.
5. Insert the new brush, fasten the screws, reposition the spring, place the brush-holders back in its original position and
tighten and adapt the brushes to the collector using a polishing stone.
Be aware that the position of the brush-holders ring will be altered during the changing procedure of the lower brushes. In order to
always leave the brush-holders ring in its original position use the existing paint mark for this purpose. In case the mark had
disappeared follow the instructions below for correct positioning of the brush-holders ring:
1. Disconnect all external connectors.
2. Energize the excitation terminals F1 and F2 with 220VAC.
3. Connect AC voltmeter to terminals A1 and A2 (a minimum scale of 2 Volts is required).
4. Check the voltmeter measure and turn the brush-holders ring clockwise or counter-clockwise until it reads 0 Volts.
When that happens, the brush-holders ring will be in the right position.
Brush dimensions and quality are described in the technical data sheet of each motor.
6.2.6 Cleaning the collector area
Blow with compressed air in the collector area to prevent the accumulation of dust produced by the wear of the brushes; for this it
is necessary to remove the side protections of the rear shield.
It is recommended to carry out this action twice a year for the motors equipped with IP23 and every 500 hours for the motors
superior to IP44.
6.3 Replacing the encoder/tacho
1. Remove the protection
2. Loosen the elastic coupling that connects the shafts
3. Remove the stator flange
4. Remove the encoder from the flange
