6.6.14 Changing the Voltage for Creep Feed (JOB 6)
Definition
By changing the voltage for creep feed (JOB 6) you can adjust the speed for creep feed.
Supply the control interface with the new creep feed voltage and activate JOB 6.
You can set a voltage between 0 V and 11.7589 V (including overrange) in S7 analog value
format (you will find a detailed explanation in the
Distributed I/O Device manual).
The 1PosSSI/Analog accepts the preset voltage. The voltage remains valid until the
parameter assignment of the PosSSI/Analog is changed.
Effect on the MODEs
MODE What Happens
Inching -
Absolute Positioning
Relative Positioning
When the drive runs in creep feed, it accelerates/decelerates at the set
acceleration/deceleration rate to the new creep feed voltage.
