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

P-AXIS-00337

Numerator of scaling factor for jerk feedforward

Description

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.

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 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…] ].
