Out Puts
| FUNCTION | PIN NAME | DESCRIPTION | ELECTRICAL SPECS. |
|---|---|---|---|
| POWER/MOTOR | GND | GND. Connect the negative end of Power Supply here | GND |
| +VDC | Power. Connect Positive end of Power Supply here. DO NOT EXCEED MAX VOLTAGE RATING OF 80VDC! | Voltage Input: 12 - 80VDC | |
| B- | Phase B Bar Motor Connection | Phase currents from 0.8 to 10A Peak Current Chopping Frequency: 22KHz | |
| B | Phase B Motor Connection | Phase currents from 0.8 to 10A Peak Current Chopping Frequency: 22KHz | |
| A- | Phase A Bar Motor Connection | Phase currents from 0.8 to 10A Peak Current Chopping Frequency: 22KHz | |
| A | Phase A Motor Connection | Phase currents from 0.8 to 10A Peak Current Chopping Frequency: 22KHz | |
| LOGIC | GND | Logic GND | GND |
| COM (Input) | Opto Common input. Used to Optically Isolate the Input when a separate supply is connected. Connecting the +5VDC will make the Inputs Functional but the Inputs will NOT be Isolated. Note COM needs to be powered either by a separate supply or the +5VDC Pin in order for the Input/Outputs to function. | Voltage: 3 - 24 VDC Max Current: 20mA | |
| DISABLE (Input) | Used to Disable drive. Active Low. A closed connection to GND will Disable the drive. This is a Sink or Source Input | Voltage: 3 - 24 VDC Max Current: 20mA | |
| STEP (Input) | The Step output from a Pulse Generator is Input into this pin. Both an NPN and a PNP type PLC can be used for this input. Refer to Connection Diagrams for help | Voltage: 3 - 24 VDC Max Current: 20mA | |
| DIR (Input) | Used to switch Direction of motor. Active Low. A closed connection to GND will change direction. This is a Sink or Source Input. | Voltage: 3 - 24 VDC Max Current: 20mA | |
| +5 VDC (Input) | Internal +5VDC Output. If Optical Isolation is not desired then it can be connected to COM Pin. DO NOT USE FOR EXTERNAL CIRCUITRY! | Voltage: 5 VDC Max Current: 80mA |
