Maintenance
- 9 -
Do not try to increase motor speed by changing parameter settings in the speed controller; it can cause
accident and severe damage to the motor.
SEPEX speed controls are protected by a diode in the power circuit to filter inductive loads in the event
of a sudden power interrupt. Some speed controllers require a diode to filter inductive loads on the KSI
input. Removing the diodes will cause the speed control failure.
Before resuming maintenance operations, inspect safety warnings stickers and replace any if damage is
found and part of the text can’t be read.
Check decals and labels, see “DECAL AND LABELS” page.
