System Description
1.1.3 Compatibility with 637 Servo Drives (Not required for new projects)
The 637f series servo drives are essentially pin- and functionally compatible with the servo drives 637.
However, when a servo drive 637 is replaced with a 637f drive, the existing application must be checked and
carefully tested to determine compliance under the corresponding safety precautions.
The following points should be checked in any case and eventually be adjusted before the function test:
1. Motor direction parameter and limit switch setting (see release note V6.12)
2. Position setpoints and comparison values have to be quadrupled, resp. sixteenfold
(low encoder resolution at 637)
3. Coupling factors in synchronous applications have to be quadrupled, resp. sixteenfold
(low encoder resolution at 637)
4. Execution of BIAS- and PLC programs is 2.25 times quicker than with the 637. This can cause timing
problems with improper programming (e.g. wait times with NOPs)
