SECTION 2.1
Logic Interface and Connection
Optically Isolated Logic Inputs
The MDriveAC Plus
Microstepping 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 optocou-
pler supply and may be
connected to sinking or
+5 to +24 VDC sourcing
outputs on a controller or
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.
