Jogging
Two of the Si5580 input terminals are provided for jogging the motor. The inputs are labeled “JOG
CW” and “JOG CCW”. Activating one of the inputs commands the drive to move the motor at a pre-
designated speed until the contact is opened. A relay or mechanical switch can be used to activate
the jog inputs. 5-24 volt circuitry can be used. The schematic diagram of the input circuit is shown
below.
If you’re using a switch or relay, wire one end to the JOG input and the other to the power supply
negative (-) terminal. Then connect the COM input to the power supply positive (+) terminals.
Limit Switches
The Si5580 has two limit switch inputs, LIMIT CW and LIMIT CCW. By connecting these inputs to
switches or sensors that are triggered by the motion of the motor or load, you can force the Si5580
to operate within certain limits. This is useful if a program error could cause damage to your system
from the motor traveling too far.
As the limit inputs of the Si5580 are optically isolated, you can choose a voltage between 5-24 Vdc
to apply to your limit circuitry. This allows you to have long wires on limit sensors with less risk of
intoducing noise to the Si5580 (choose 12-24 Vdc for best noist immunity). The power light will blink
if a limit switch is activated. The schematic diagram of the limit switch input circuit is shown below.
