Configuration
The threshold values for the first stage of the synchronous operation monitoring will be
adjusted:
● For setpoint / actual value coupling in the machine data:
– MD37200 $MA_COUPLE_POS_TOL_COARSE (threshold value for "coarse
– MD37210 $MA_COUPLE_POS_TOL_FINE (threshold value for "fine synchronism")
● For speed coupling in the machine data:
– MD37220 $MA_COUPLE_VELO_TOL_COARSE ("coarse" speed tolerance)
– MD37230 $MA_COUPLE_VELO_TOL_FINE ("fine" speed tolerance)
Programming
CP keywords can also be used to program the threshold values for the first stage of the
synchronous operation monitoring:

CPSYNCOP[FAx]= <value>
Coupling Synchronous Difference Coarse Position
Defines the threshold value for the "Coarse' position synchronous op‐
eration.
Type:
The default value corresponds to the setting in the machine data:
MD37200 $MA_COUPLE_POS_TOL_COARSE [FAx]
CPSYNFIP[FAx]= <value>
Coupling Synchronous Difference Fine Position
Defines the threshold value for the "Fine" position synchronous oper‐
ation.
Type:
The default value corresponds to the setting in the machine data:
MD37210 $MA_COUPLE_POS_TOL_FINE [FAx]
