Devices with “Jogkeys” option
External jog buttons can be used to move the drive when the bus connection is
inactive.
When the bus connection is active, the external jog buttons can be enabled via bits 3
and 5 in the control word (see section

).
The step size for short keystrokes can be set via parameter SDO # 2022. A single
step is executed when one of the external keys is pressed. If the key is released
before the single step has been completed, it will still be completed. If the same key
remains pressed, the single step may be followed by a continuous manual movement
after a short waiting time, which continues as long as the key is pressed. The waiting
time until the drive changes over to manual travel is set with SDO # 2022. In manual
travel, the drive moves to the respective limit switch position (SDO # 2016 + 2017).
If both keys are pressed during a jog movement, the movement is aborted
immediately. A new inching movement is only possible again when both keys have
been released.
Connecting the Jog Key Inputs
The jog key inputs can be used in 2 different wiring modes:
- Connection of potential-free switches
To activate the respective jog key input, the +24V in the jog key plug is connected
here.
The GND connection in the jog key plug remains unused.
The 24V output in the jog key plug is internally connected to the +24V control in the
supply plug. It is therefore also possible to connect the jog button inputs directly to
the +24V control potential via switches.
- Connection of an active signal
Here the respective jog key input is connected to the (active) signal connection.
The reference ground of the external active signal should be connected to the GND
connection in the jog key plug.
The +24V output in the jog key plug remains unused.
The GND connection in the jog key plug is internally connected to the GND control
in the power supply plug. If the connected active jog key signal has the same GND
potential as the GND control, the wiring of the GND connection in the jog key plug
can be omitted.
Connection examples:
potential-free switches
active signals e.g. from a PLC
