1 Introduction
The stepper-motor-controller iMC-S8 is a freely programmable compact control up to
four linear or rotational units with 2-phase stepper motors. The controller integrates
maximum four motor power amplifiers with step/direction interface, a processor core
with flash memory to interpret the user programs and generating step/direction signals
for the power amplifiers, power supply units, security circuit module and a table
housing with net input filter and control elements.
1.1 Intended use
The processors operating system (firmware) provides following operation modes:
DNC-mode:
The controller is permanent connected with a PC/laptop via serial interface.
CNC-mode:
The controller works „Stand Alone“ after a user program is downloaded to the
processors flash memory.
The controller is able to drive stepper-motors in micro stepping mode. The power
amplifiers generates up to 128 micro-steps per full-step. This allows a smoothly run of
the connected motors. An automatic current reduction reduces the power loss in the
amplifier and motor.
The peak current amounts 7,8A and is adjustable via DIP-switches.
With the impulse input it’s possible to control the most important functions (start,
stop). Thereby it’s also possible to connect an external control console or a higher
ranked control (e.g. PLC).
All axis of the controller have to be used only with the compatible motor type.
Please read this operation instruction manual carefully before first use of the controller
therewith you can:
•Work safely, fast and effective
•Keep away danger from persons
•Use all the power and features of the controller.

1.2 Safety instructions
The stepper-motor-controller iMC-S8 is designed in conformability to
current technical and recognized rules.
The device may only be used if it is in correct condition. Any faults
have to be eliminated immediately. Neither children nor non-
authorized persons are allowed to put the device into operation.
The device may only be used for the intended purpose: control of 2
up to 4 linear or rotational axes with 2-phase stepper motors.
All work with the controller iMC-S8, especially initial operation,
installation as well as external wiring must be executed by authorized
personal regarding electrical industry rules and accident prevention
regulations.
Assembly and use of operating material has to be according to EMC
directive 2014/30/EC and Low voltage directive 2014/35/EC. In case
of in proper use even the observation of the respective rules and
standards does not protect against physical damages and damage to
property.
Do not expose the device to high humidity or high vibrations.
Please take care of the instruction manual. Be sure that all users
know the instructions.
Ignoring the instruction manual can lead to damage, heavy physical
damage or to death.

Warning! High earth leakage current (ground discharge current,
protection conductor current). Before connecting to the AC supply
network, it is necessarily required an additional protective grounding.
Before connecting the CNC controller to the AC supply network, an
additional protective grounding (cross section: 2.5 mm2or 4 mm2,
see below) has to be connected! Before the electrical start-op of the
controllers a protective grounding of 2.5 mm2(protected installation) or a
protective conductor of 4 mm2(unprotected installation) has to be
connected durably to the marked clamping point at the back of the
housing where the cross section of the protective grounding shall not be
less than 10 mm2copper or 16 mm2aluminum has (e.g. electrical
distribution of the building). Please instruct an electrician with these
implementation. When using the Residual Current circuit Device (RCD)
for line fuses/fault current delimitation: Do not use an RCD with AC
characteristics. Using a frequency inverter and choppered power stages
in the power units may cause superimposed AC fault units with pulsating
direct current and direct current apart from AC fault currents. Please
consult your electrician.
The term leakage is understood here as grounding discharge
current. This is defined in the standard EN 60204-1:2006 section
8.2.8, note 1
If the CNC machine (ideal) is set up isolated from the reference
potential, the grounding discharge current is equal to the
protective grounding stream.
