637+/D6R22-7-CAN - Servo Controller - EUROTHERM
This 637+/D6R22-7-CAN reference drive and the EUROTHERM brand is a 637 series drive.
This 637 digital drive is designed for the control of brushless motors equipped with a resolver as standard. It can be controlled in torque, speed or position.
This EUROTHERM drive is at your disposal to replace your defective equipment and has a guarantee adapted to your needs.
The 637f drives are to a large extent compatible with pinouts and functions with the 637 Series.
However, when a 637 drive is to be replaced with a 637f drive, the existing application should be carefully checked and tested to ensure full compatibility.
The following points must be checked in all cases and possibly adapted during functional tests:
1. Motor direction setting and limit switch setting (see V6.12 update note)
2. Position setpoints and associated comparison values should be multiplied by 4 (637 with lower encoder resolution)
3. Copy reports in master / slave applications should be multiplied by 4 (637 with lower resolution encoder)
4. Execution of "BIAS" and "PLC" programs 2.25 times faster than with a 637 drive. This can pose potential problems related to time management in case of inappropriate programming (eg timers using NOPs ).
