    C32 (Rev. 5) User Manual BOARD DESCRIPTION POWER TERMINALS AND CONFIGURATION JUMPERS Before connecting the power supplies, follow steps below. Power terminals and configuration Jumpers for inputs These opto-isolated inputs require an external 5VDC to be powered. It is recommended when isolation between PC and power of inputs is required (set jumpers in REQUIRED position).

  • Page 6: Power Terminals And Jumper For Driver Monitor Circuit

    C32 (Rev. 5) User Manual If isolation is not required, don't connect any external power supply to these terminals and set jumpers in "NOT REQUIRED" position. Power terminals and Jumper for Driver monitor circuit Connects an external (5V) power supply, when using drivers with error or alarm signal common to its power GND.

    C32 (Rev. 5) User Manual CONFIGURATION DIPSWITCH DIPSWITCH allows activating or deactivating the SCHP detection function, and selecting the driver to use and delays an enable signal for external devices. 5.1 Position 1 The enable output (Pin 17-Port 2) will be activated when the driver enable process starts.
  • Page 9 C32 (Rev. 5) User Manual Onboard DIPSWITCH allows activating or deactivating the SCHP detection function. SWITCH 2 ON: Activate the SCHP detection function. SWITCH 2 OFF: Deactivate the SCHP detection function. When the Safety Charge Pump function is activated, 5V are present in the E-Stop Note: terminal and a valid SCHP signal is present, Port 2 Pin 17 will go high.

    Operation Mode 1 (G320/DG4S) When the system starts, the C32 error/reset pins go to a low state (0V), making sure the driver remains disabled. When SCHP and E-Stop function are checked and validated and there is no fault signal coming from any driver, the system sends a high (5V) to the driver’s error/reset pins for about 5 seconds to enable the drivers.

    C32 (Rev. 5) User Manual Operation Mode 4 (Viper, Teco and Delta) When the system starts, the C32 enable pins go to a low state (0V). When SCHP and E-Stop function are checked and validated and there is no fault signal coming from any driver, the system sends a high (5V) to the driver Fault output pin, enabling the drivers.

  • Page 12: Operation Mode Selection Jumper

    C32 (Rev. 5) User Manual 7.1 Operation Mode Selection Jumper This jumper allows selecting the way how the relays are activated when a PWM signal and REV signal are present in the pins 1_14 and 1_16. In US mode one relay is used to start on CW and the other one to start on CCW. In international mode one relay is used for on/off, and the other one to indicate the CW or CCW rotation of the spindle motor.
