General

The iMC-S8 step controller is a freely programmable compact controller for linear or circular axes with 2-phase step motors.

The controller integrates all the necessary components (power supply, safety circuit, power electronics, core  processor, interfaces, operating elements) that are needed to control individual spindles all the way to entire machines. It has an intelligent core module that is controlled and programmed via a RS232 interface.

The core module also converts the commands programmed in the user program into clocking/direction signals for the connected final stages. Depending on the purpose, the iMC-S8 controller can be used either in CNC or in DNC mode.

In CNC mode, the processor processes the CNC program which was previously produced with PAL-PC and stored in the controller's Flash memory.

In DNC mode, the iMC-S8 controller is connected permanently with a control computer (PC, laptop) via a serial interface (RS232). Processing is carried out via the isel control software Remote.

• 32-bit RISC processor with Flash memory for user program 
•  Final output stages
  - Step resolution and motor current adjustable via variable DIP switch
  - automatic current sink
• Acceleration, start-stop frequency and step output frequency variable
• both hardware limit switches configurable
• Door controller/hood controller
• Control elements in the front of the casing
• external EMERGENCY SHUTDOWN andPOWER connection for integration inhigher level safety circuits
• Connection for external control signals, such as START, STOP, RESET (only CNC mode)
• 230V connection for milling spindle(100-230V AC)
• 0 .. 10V analogue output for externalfrequency converter for speed-controlled main spindle
• Programming/Operation
  - PAL-PC in CNC mode (in the scope ofdelivery)
  - Remote (optional: ProNC) in DNC mode- isel @ - format in CNC/DNC modes
