Digital Inputs (optional)
The Gem6K drive has five digital inputs. All connections are shown in the next
drawing. By default, all inputs are configured as general purpose inputs. Use the
INFNC command to redefine the function of any of the inputs. For more informa-
tion, see the
Gemini GV6K/GT6K Command Reference
.
By default, these are +24VDC sourcing inputs. You can use VINref (pin 26) to
change the switching voltage level. You can also use CNTRL-P (pin 33) to change
the inputs from sourcing to sinking inputs.
Should you choose to use the Trigger A, Trigger B, or Master Trigger functions,
you must assign them to specific inputs, as follows:

Inputs internally pulled up to
+24V, unless you connect an
external 5 – 24VDC supply to
the VINref terminal.
Inputs are sourcing at +24V,
unless you connect CNTRL-P
to ground; then inputs will be
sinking inputs.

Inputs
You can use the INLVL and INDEB commands to configure the inputs as active
high or active low, and to set the debounce time, respectively.
