3.8.3.
During the setting procedure, it is strictly necessary to respect the 3 following conditions:
Resolver setting
- The rotor must be able to rotate freely. The maximum friction torque on the rotor
must not exceed 1% of the motor permanent torque.
- The cooling circuit has to be in use.
- The operator must be able to reach the resolver stator and to manually turn it and
lock it (access to the locking screws).
Look at the DIGIVEX instruction manual for the setting procedure details.
3.8.4.
1V~, 250Khz max
Sin-Cos Encoder (on request)
Restriction:
As the encoder is not absolute on one turn, the setting is lost at each power
OFF. You must either set the encoder at each power ON or keep alive the low power
supplies.
The advantage of the sin-cos encoder is the excellent accuracy that allows very good
power, speed and position control.
