Logic Interface and Connection
MDriveAC Plus Microstepping Optically Isolated Logic Inputs
The MDriveAC Plus has three optically isolated
logic inputs which are located on connector
P1. These inputs are isolated to minimize or
eliminate electrical noise coupled onto the
drive control signals. Each input is internally
pulled-up to the level of the optocoupler supply
and may be connected to sinking outputs on
a controller such as the IMS LYNX or a PLC.
These inputs are:
1] Step Clock (SCLK)/Quadrature
(CH A)/Clock UP
2] Direction (DIR)/Quadrature
(CH B)/ Clock DOWN
3] Enable (EN)
Of these inputs only step clock and direction are
required to operate the MDriveAC Plus Microstepping.
Isolated Logic Input Pins and Connections
The following diagram illustrates the pins and connections for the MDriveAC Plus Microstepping family of prod-
ucts. Careful attention should be paid to verify the connections on the model MDriveAC Plus Microstepping you
are using.
Isolated Logic Input Characteristics
Enable Input
This input can be used to enable or disable the driver output circuitry. Leaving the enable switch open (Logic
HIGH, Disconnected) for sinking or sourcing configuration, the driver outputs will be enabled and the step clock
pulses will cause the motor to advance. When this input switch is closed (Logic LOW) in both sinking and sourc-
ing configurations, the driver output circuitry will be disabled. Please note that the internal sine/cosine position
generator will continue to increment or decrement as long as step clock pluses are being received by the MDriveAC
Plus Microstepping.
Clock Inputs
The MDriveAC Plus Microstepping features the ability to configure the clock inputs based upon how the user will
desire to control the drive. By default the unit is configured for the Step/Direction function.
Step Clock
The step clock input is where the motion clock from your control circuitry will be connected. The motor will
advance one microstep in the plus or minus direction (based upon the state of the direction input) on the ris-
