2.1 MAIN SPEED POTENTIOMETER CONNECTION:
Wire the Main Speed Potentiometer to Terminal Block TB1 on the SIVFR. See Section 2.3, on page 6, for Forward-Stop-Reverse
Switch (or Jumper) connection. If a Forward-Stop-Reverse Switch is not used, a jumper must be installed between Terminals “0V”
and “FWD”, of Terminal Block TB1, in order for the drive to operate.
Unidirectional Speed Operation: Wire the Main Speed Potentiometer to Terminals “+5V” (high), “SIG1” (wiper), “COM1” (low).
Motor direction is selected with a Forward-Stop-Reverse Switch wired to Terminals “0V” (common of switch), “FWD”, “REV”. Set
Jumper J1 to the “VOLT” position. See Figure 9.
Bidirectional Speed Operation: Wire the Main Speed Potentiometer to Terminals “+5V” (high), “SIG1” (wiper), “-5V” (low).
Terminals “FWD”, “REV”, “COM1” must be hard wired together. Set Jumper J1 to the “VOLT” position. See Figure 10.

2.2 SIGNAL FOLLOWING CONNECTION: The drive output will linearly follow the analog signal input. The SIVFR is factory calibrated
for 0 to ±5 Volt DC signal input. Wire the voltage (0 to ±2.5 thru 0 to ±25 Volt DC) or current (4 – 20 mA DC) signal input to
Terminals “SIG1” (+) and “COM1” (-) of Terminal Block TB1 on the SIVFR. A jumper must be installed between Terminals “0V” and
“FWD”, of Terminal Block TB1, in order for the drive to operate.
For voltage following, be sure Jumper J1 (on the SIVFR) is set to the “VOLT” position (factory setting). See Figure 11.
Application Note: In the Voltage Following Mode, the input will accept a “+” and “-“ input voltage, which will run the motor in the
forward and reverse direction.
For current following, set Jumper J1 (on the SIVFR) to the “CUR” position. See Figure 12. Also See Section 3.2, on page 7.

2.3 FORWARD-STOP-REVERSE SWITCH CONNECTION: Wire the Forward-Stop-Reverse Switch as shown in Figure 9. If using
Form “C” Contact or Relay, wire the circuit as shown in Figure 13. If using Open Collector, wire the circuit as shown in Figure 14.
