Numerator of scaling factor for jerk feedforward (P-AXIS-00337)

P-AXIS-00337

Numerator of scaling factor for jerk feedforward

Description

This parameter specifies the numerator of the scaling factor for jerk feedforward control. The scaling factor for jerk feedforward control is defined as:

jerk_fact = P-AXIS-00337/P-AXIS-00338

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

Parameter

vorsteuer.jerk_fact_num

Data type

UNS32

Data range

0 ≤ jerk_fact_num ≤ MAX(UNS32)

Axis types

T, R, S

Dimension

T: ----

R,S: ----

Default value

1

Drive types

----

Remarks

Jerk feedforward control 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.

For details on defining the acceleration profile, see P-CHAN-00071 and [PROG//Command #SLOPE [TYPE…] ].
