4. Connecting Control Signal
The iSS57 accepts both differential and single-ended inputs (including open-collector and PNP output). Choose
suitable connections type according to the controller type. Make sure the output port of the controller can sink or
source at least 10mA current for the input isolated opto-coupler. If the cable length is greater than 50cm, it is
recommended to use twisted shielded pair cable for these signal. Do not put the control signal cable together with the
cables which is used for high power or high current equipment, in case of electronic interference coupled into the
iSS57 through air.
NPN Signal Connections
If the motion controller is not differential
output type, recommended to select
motion controller with NPN type output
as it can sink more current than source
current. In this connection, Pulse,
Direction and Enable signal share the
same VCC (Positive) terminal.
PNP Signal Connections
In this connection, Pulse, Direction and
Enable signal share the same ground
(negative) terminal.
Differential Signal Connections
For differential output controller, connect
to the integrated stepper accordingly.
