4.6.13 Changing the Voltage for Rapid Feed (JOB 5)
Definition
By changing the voltage for rapid feed (JOB 5) you can adjust the speed for rapid feed.
Supply the control interface with the new rapid feed voltage and activate JOB 5.
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 1PosInc/Analog accepts the preset voltage. When the drive runs in rapid feed, it
accelerates/decelerates at the set acceleration/deceleration rate to the new rapid feed
voltage. The voltage remains valid until the parameter assignment of the 1PosInc/Analog is
changed.
