EINSTELLUNGEN
The pendant can be operated with all ELS4 Pro and Basic from software version 11. If the soft-
ware is older, an update must be installed rst!
The rotary encoder on the pendant allows the axes to be moved stepwise but also permanent-
ly, so there is a step mode and a move mode. The axis must rst be activated by pressing XSTEP
or ZSTEP. The selected axis then moves analog to the direction of rotation on the encoder. If
you crank quickly, the system switches seamlessly from stepping to moving mode.
The step size in step mode is set in the ELS settings, via SETUP DATA -> STEPS 1 and STEPS 2
The driving speeds in driving mode are set in the respective axle drives under SETUP Z/X-MO-
TOR -> F SLOW < > and F RAPID << >>.
In version 6 you will nd a new group EXPANSION in the settings, where there are 6 parameters
that determine the response of the encoder. They are preset to values that are well suited for
an encoder with 100 pulse revolutions as present in the pendant.
ON-THRESHOLD TIME (0,1-8,0 ms, 4,0 ms=Standard)
This is the time that must elapse between two successive pulses from the encoder for the ro-
tary motion to be classied as „slow“. Slow pulses lead to single steps of the axis. If the pulses
come faster, they are classied as „fast“. If the number is high, you have to crank slower to
switch to drive mode, if the number is low, you have to crank faster.
If the number of fast pulses received without interruption is higher than
ON-THRESHOLD COUNTER (1-500, 100=Standard)
the axis is switched to drive mode, it then drives permanently.
If the number is high, you need more fast impulses to switch to driving mode‘, so you have to
crank longer fast.
If you stop turning abruptly, the axis also stops after the
OFF-THRESHOLD TIME (1-350 ms, 100=Standard)
This is the time after which the axis is switched back from drive mode to step mode. 100 ms is
a good time, if you want faster reaction you can lower it.
To avoid leaving the driving mode again and again due to slight uctuations when the encoder
is turned quickly, which would result in a very jerky driving picture, there is a threshold setting,
the number of pulses in
OFF-THRESHOLD COUNTER (1-500, 20=Standard)
indicates how many slow pulses must be received in succession in order to leave the driving
mode. Higher values allow you to crank very unstable, lower values allow you to leave the driv-
ing mode quickly when cranking slower.
REPEAT-TIME (1-500 ms, 100 ms=Standard)
Concerns only rides away from material. If the encoder is turned slowly for a longer period of
time, several single steps are output one after the other. This parameter indicates the time that
must elapse after the last step to compensate for backlash.
