Limit Switches
The FSC-01 has two limit switch inputs, LIMIT CW and LIMIT CCW. By connecting switches or
sensors that are triggered by the motion of the motor or load, you can force the FSC-01 to operate
within certain limits. This is useful if a program error could cause damage to your system by
traveling too far.
The limit inputs are optically isolated. This allows you to choose a voltage for your limit circuits of
5 to 24 volts DC. It also allows you to have long wires on limit sensors that may be far from the
FSC-01 with less risk of introducing noise to the FSC-01. The schematic diagram of the limit
input circuit is shown below.
Front Panel Stop Button
On the front panel of the FSC-01 is a button marked “STOP.” This button can be used to interrupt
motion at any time. After pressing the STOP button, the output pulses to the motor driver will stop.
The front panel Power LED will then flash until the AC power is removed from the indexer. If the
FSC-01 is connected to a PC running the Windows Programming Software, the software will alert
the user on screen to the condition, and ask if you want to reset the indexer from the PC.
Jogging
Two of the FSC-01 input terminals are provided for jogging the motor. The inputs are labeled “JOG
CW” and “JOG CCW.” Taking one of the inputs low commands the drive to move the motor at a
pre-defined speed until the contact is opened. A relay or mechanical switch can be used to activate
the jog inputs. 5 volt circuitry can also 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 24V GND
terminal. Then connect the IN/JOG COM and +24 VDC terminals.
