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

P-AXIS-00338

Denominator of scaling factor for jerk feedforward

Description

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.

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 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 #SLOPE [TYPE…] ].

A value of 0 is inadmissible for this parameter. If zero is set up as value an error message with error-id 110473 is output and the parameter is set to its default value (100).
