Numerator of scaling factor for jerk feedforward (P-AXIS-00337)
With this parameter the numerator of the scaling factor for jerk feedforward 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.
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-00071removed link: P-CHAN-00071and [PROG - command #SET SLOPE PROFIL]removed link: [PROG - command #SET SLOPE PROFIL]. |
