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

P-AXIS-00338

Denominator of scaling factor for jerk feedforward

Description

This parameter specifies the denominator 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_denom

Data type

UNS32

Data range

0 < jerk_fact_denom ≤ MAX(UNS32)

Axis types

T, R, S

Dimension

T: ----

R,S: ----

Default value

100

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…] ].

A value of 0 is inadmissible for this parameter. If this value is specified nevertheless, an error message with error code 110473 is output and the value is corrected to the default (100).
