NC MD 1396* modifies NC MD 155 ”Position controller sampling time”, i. e. the controller can
be slowed down by a factor of 2 to 64.
Permissible values:
1, 2, 4, 8, 16, 32, 64
The following applies:
Position control cycle time = Position control basic cycle x MD 1396*
Interpolation cycle
Conditions: –––––––––––––––––––– >1 (integer)
