Denominator of scaling factor for jerk feedforward (P-AXIS-00338)

With this parameter the denominator of the scaling factor for jerk feedforward is is set. The scaling factor for jerk feedforward is defined as:

jerk_fact = P-AXIS-00337/P-AXIS-00038

The output of the jerk feedforward command value to the drive has to be activated by setting bit 0x04 in axis parameter P-AXIS-00223.

Denominator of scaling factor for jerk feedforward (P-AXIS-00338) 1:

Jerk feedforward is only possible if a jerk limited acceleration profile is used. For non jerk limited acceleration profiles a jerk command value of 0 is output.Further informations on the definition of the acceleration profile to use can be found in P-CHAN-00071 and [PROG - command #SET SLOPE PROFIL].
