Function

The SEL0 (pin1), SEL1 (pin2) and SEL2 (pin3) inputs are used to select the communication protocol and

the module address. They have an internal pull-up and when unconnected they are at the 1 logic level.

The BR0 (pin4), BR1 (pin5) and BR2 (pin6) inputs are used to select the Baud rate of the

communication port. They have an internal pull-up and when unconnected they are at the 1 logic level.

The CHS checksum generation conditioning input enables the user to include or exclude the checksum

character from the data exchange string. A ”zero” logic level applied to this input disables the control and

the generation of the checksum character thus allowing the GS-C to be connected to a video terminal.

This pin is the common terminal for all logic signals and for the power supply return path.

The REC Recall Program Enable input pin, when brought to ”zero”, enables the automatic recall of the

program stored in the EEPROM and its immediate execution.

This pin is for testing purpose only and it must be grounded for normal operation.

The RxD input of the serial communication port is used by the module to receive commands from the

Host Computer. The input logic levels are compatible with the RS232 and V24 standards.

The TxD output of the serial communication port is used by the module to send data to the Host

Computer. The logic levels of this output are compatible with the RS232 and V24 standards.

The TxPD Transmitted data pull-down resistor pin must always be connected to the TxD output (pin 12)

when the Point-to-Point protocol is used. When the Multipoint protocol is selected, this pin must be left

open on all modules except the chain terminator unit, in order to avoid the TxD output overload.

The RDY hardware status output (open collector) signal pin is used as the controller status flag. RDY

assumes a ”zero” logic level when a command or a program is in execution

–12V unregulated output. A maximum of 10mA can be sinked from this pin.

+12V unregulated output. A maximum of 10mA can be sinked from this pin.

Module supply input. For correct operations a supply voltage ranging from 12 to 40 Volt is required.

See pin 8.

5 Volt regulated output, available either for the Sequencer-Driver logic section or for a custom interface

logic supply. The maximum current that can be sinked from this pin is 100mA.

The MOV Motor moving output becomes the logic level ”one” when the GS-C is executing a movement.

This output can be used to program the phase current level when the motion is running at a level higher

than for the rest condition.

The RAMP Ramp in execution output is rised to the logic level ”one” when the GS-C is executing an

acceleration or a deceleration ramp. This output can be used to program the phase current level when

the motion is ramping at a level higher than for the rest or slewing condition.

The ENABLE input pin allows the user to control the Step clock logic output to avoid the motor being

stepped if the previous step was not correctly executed. A ”zero” logic level applied to this pin stops the

generation of the step pulses. This input can be used to stop the system when an emergency occurs, to

execute the motion according to externally generated timing, or to implement a closed loop control

system.

Not connected.

The DIR Direction selection output is used to inform the Sequencer-Driver on the direction of rotation.

The logic level ”one” determines a clockwise rotation, but of course the rotation depends on the motor

phases connection to the Sequencer-Driver.

The RESET Power driver Reset output is brought to the ”zero” logic state for 400µs when the unit is

powered-on, or when the GS-C receives the ”Initialize position counter” command. This output is

normally used to assure the correct start-up of the Sequencer-Driver or any other external custom logic.
