How to control the drive through the I/O interface
The table below instructs how to operate the drive through the digital and analogue
inputs, when the default parameter settings are valid.
Preliminary settings
Ensure the control connections are wired according to the
connection diagram given in chapter
Application macros .
Switch to external control by pressing the LOC REM button on
the control panel. (External control is indicated by the text
“REM” on the uppermost row on the display.)
Starting and controlling the speed of the motor
Start the drive by switching digital input DI1 on. Digital input
status can be monitored with signal
02.01 DI status .
02.01 DI status
Check that analog input AI1 is used as a voltage input
(selected by jumper J1 on the JCU Control Unit).
Regulate the speed by adjusting the voltage on analogue input
AI1.
Check analogue input AI1 signal scaling. AI1 values can be
monitored with signals
02.04 AI1 and 02.05 AI1 scaled .
When AI1 is used as a voltage input, the input is differential
and the negative value corresponds to the negative speed and
the positive value to the positive speed.

Stopping the motor
Stop the drive by switching digital input DI1 off. 02.01 DI status
