Control Elements
– connector for control elements, Sub-D-25 pin
Connector for the control elements (buttons, switches) from the front side of the machine.
RS232 (PC)
– programming interface
Communication between iMC-M / iMC and control PC is realized via a serial interface
(RS232). Use the delivered communication (null modem) cable for connection.
A software protocol realizes the faultless transmission of the ASCII characters. Therefore
it’s necessary that both systems respect the communication protocol:
The connected control PC sends a command which ends with a line end character
[CR, char (13)].
The processor unit quits the execution or storing of a command with the quitting
signal 0[char (48)] or returns an occurred error with an ASCII character unequal 0.
Data transfer parameters:
- 19200 baud
- 8 data bits
- 1 stop bit
- no parity

Adjusting the stepper motor power amplifiers
The CNC machine ICP 3020/4030 iMC-P has four stepper motor power amplifiers MD24.
Settings for rated current, step resolution and current reduction takes place by the DIP-
switch on the top side of the amplifiers case.
When delivered, all stepper motor drives are set to the corresponding stepper motors of
your machine. If it is still necessary that you have to change the settings of the stepper
motor power stages (e.g. use of a 4th axis) note the following pages.
Configuration of the controller should be done before first start-up so that
a connected motor will not be damaged because of an incorrect power
setting.
