  • Page 14: Unit Functions 1

    UNIT FUNCTIONS RUN/STOP: A closed contact between the RUN and V+ will start the control as long as the INHIBIT is not activated. At the time of the START command, the unit will follow the adjustable ACCEL ramp to the Speed Input setting.
  • Page 15 *Verify that INHIBIT Is properly wired for application. See pages 14 & 15 for details. NOTES: 1. Factory set at 0 Vdc. 2 . Factory set for 90 Vdc for 120V controllers, 180 V dc for 240 V controllers. 3 . Factory set for 100% of controller rating. 4 .

  • Page 19: Wiring 1

    WIRING 1 . Refer to Ratings Chart (pg 8) for incoming line current and fuse rating. It is the responsibility of the user or person installing the controller to provide branch circuit protection according to NEC and local codes. On controllers using 120 VAC input, be sure the incoming hot lead is connected to L1 and common is connected to L2.

    6 . WARNING: ALL TERMINALS OF THE UNIT ARE AT LINE POTENTIAL AND CAN BE EXTREMELY: HAZARDOUS. POWER MUST BE REMOVED FROM UNIT BEFORE ANY WIRES ARE CONNECTED. FAILURE TO COMPLY MAY RESULT IN PERSONAL INJURY, EQUIPMENT FAILURE, OR BOTH. 7 .
  • Page 21 2 . Set the Speed Pot to Minimum Speed (CCW), and place the external RUN/STOP switch in the STOP position 3 . Apply power to the control. Place the RUN/STOP switch in the RUN position. The RUN (green) LED should glow, but the motor should not turn.

  • Page 23: Set-Up Procedures 2

    SET-UP PROCEDURES The Vari Speed S1000 has been set up at the factory to satisfy most application needs. You may, however, wish to tailor your control specifically to your application requirements. If so, follow these instructions for proper set-up. FACTORY SETTINGS...
  • Page 24 CURRENT (TORQUE) LIMIT ADJUST (CL) (Clockwise Increases Current) There are two methods for adjusting CL. METHOD 1: 1 . Start the machine and run at desired speed, then apply maximum load to the motor and turn CL trimpot fully clockwise. 2 .
  • Page 25 IR COMPENSATION ADJUSTMENT (IR) (Clockwise Increases Compensation) This adjustment is provided to overcome the motor’s natural tendency to slow down with increasing load. If improved load/speed performance is required, this adjustment may be used. NOTE: In order to optimize performance with this adjustment, some means of determining motor shaft speed is required.
  • Page 26 MINIMUM SPEED ADJUSTMENT (MIN) (Clockwise Increases Minimum Speed) 1 . Turn external Speed Pot fully counterclockwise (CCW). 2 . Turn MAX Speed Trimpot fully CCW. 3 . Produce a RUN command so that the RUN LED (green) is on and adjust the MIN SPEED trimpot until desired minimum speed is set.
  • Page 27 ACCELERATION (ACCEL)/ DECELERATION (DECEL) ADJUSTMENTS Set these two trimpots for desired times. Both ACCEL and DECEL trim pots adjust from a linear .5 to 15 seconds. Acceleration rate may be extended with CL if reflected inertia is high. DECEL may be longer if reflected inertia is high.

  • Page 28: Two-Speed Application 2

    TWO-SPEED APPLICATION By using single-pole, double throw (SPDT) relay or switch, preset two-speed operation is possible. 1 . Replace external speed pot with SPDT contacts as shown below. 2. With SPDT contacts closed between terminals SP2 and SP3, adjust the MIN SPEED trimpot to desired low speed. 3.

  • Page 29: Troubleshooting Guide 2

    TROUBLESHOOTING GUIDE MOTOR WILL NOT RUN: 1 . Make sure power is applied to unit. If not, make sure disconnect fuses or circuit breaker in line are okay. 2 . Make sure RUN switch is on (RUN (green) LED should be lit). 3 .
  • Page 30 NO SPEED CONTROL: 1 . Speed pot or wiring defective. 2 . Control not set up properly (See Set-Up Procedures, pg 22) 3 . Defective control. MOTOR WILL NOT RUN AT 1725 RPM: 1 . Improper setting MAX Speed trimpot (range trimpot with isolated units).
