Connections
Pin # | Function | Description | |
Pin 1 | N/C | No Connect | |
Pin 2 | N/C | No Connect | |
|
| The Signal applied to the Optocoupler Reference will | |
|
| determine the sinking/ or sourcing configuration of the inputs. | |
Pin 3 | Opto Reference | To set the inputs for sinking operation, a +5 to +24 VDC | |
|
| supply is connected. If sourcing, the Reference is connected | |
|
| to Ground. | |
|
| Step Clock input. The step clock input will receive the clock | |
Pin 4 | Step Clock/Channel | pulses which will step the motor 1 step for each pulse. It | |
A/ Clock Up | may also receive quadrature and clock up type inputs if so | ||
| |||
|
| configured. | |
|
| Enable/Disable Input will enable or disable the driver output | |
Pin 5 | Enable | to the motor. In the disconnected state the driver outputs are | |
|
| enabled in either sinking or sourcing configuration. | |
Pin 6 | Direction/Channel B/ | Direction input. The axis direction will be with respect to the | |
Clock Down | state of the Direction Override Parameter. It may also receive | ||
| quadrature and clock up type inputs if so configured. | ||
|
| ||
Pin 7 | +5 VDC Output | Supply voltage for the | |
Pin 8 | SPI Clock | The Clock is driven by the SPI Master. The clock cycles once | |
for each data bit. | |||
|
| ||
Pin 9 | GND | Communications Ground. | |
Pin 10 | MISO | ||
to the SPI Master. | |||
|
| ||
Pin 11 | CS | SPI Chip Select. This signal is used to turn communications | |
on multiple MFM units on or off. | |||
|
| ||
Pin 12 | MOSI | ||
to the MFM. | |||
