To simplify the torque reduction commissioning, the SINUMERIK 840Di sl NC
tries to perform, as standard, an automatic adjustment using the torque reduc-
tion evaluation configured in the drive. To do this the NCK reads the relevant
drive parameters and applies the value converted to NCK format in the machine
data:
S
MD37620: $MA_PROFIBUS_TORQUE_RED_RESOL
The following requirements must be met:
S
The drive supports acyclic PROFIBUS communication.
S
The drive has a parameter to standardize torque reduction.
S
In the NCK, acyclic communication with the drive is enabled with:
– MD13070: $MN_DRIVE_FUNCTION_MASK[n], Bit 15 == 1
If the requirements for automatic adjustment of the NCK and drive are not met,
the adjustment must be performed manually in the drive and NCK.
The drive must be operated with one of the following message frames:
S
Message frame 102, 103, 105, 106 ,116
The evaluation of torque reduction is set using the parameter:
S
p1544 Torque reduction evaluation [%]
Normalization: 1% ¢16384
The following SIMODRIVE drives support high–resolution torque reduction:
S
SIMODRIVE 611 universal, universal E
S
SIMODRIVE POSMO SI, CD, CA
The drive must be operated with one of the following message frames:
S
Message frame 102 to 107
The evaluation of torque reduction is set using the parameter:
S
P0881 Torque reduction evaluation [%]
Normalization: 1% ¢16384
