– BOOST MODE SELECTION (J6)
Jumper J6 is factory set to the "FIX" position for Fixed Boost. For Adjustable Boost using the
BOOST Trimpot, set Jumper J6 to the "ADJ" position. See Figure 18 See Section 12.8 on
page 18 for the Boost Trimpot.
10.6
– BRAKING MODE SELECTION (J7)
Jumper J7 is factory set to the "RG" position for Regenerative Braking when the drive is set
to "STOP". For DC Injection Braking, set Jumper J7 to the "INJ" position. See Figure 19.
When the Injection Brake Mode is selected, the DECEL Trimpot is used to set the amount of
time the DC current is applied to the motor. See Section 12.5 on page 17.
10.7
– RUN/FAULT OUTPUT RELAY OPERATION SELECTION (J8)
Jumper J8 is factory set to the "R" position for "Run" operation of the Run/Fault Relay. For
"Fault" operation of the Run/Fault Relay, set Jumper J8 to the "F" position. See Figure 20.
For the Run/Fault Relay output contacts, see Section 7.4 on page 14. The Run/Fault Relay
contact status for various drive operating conditions is shown in Table 4 on page 14.
10.8
– STOP CONTACT TYPE SELECTION (J9)
Jumper J9 is factory set to the "NO" position for a normally open stop contact. For remote
normally closed stop contact, set Jumper J9 to the "NC" position. See Figure 21.
10.9
– TORQUE MODE SELECTION (J10)
Jumper J10 is factory set to the "VT" position for Variable Torque Mode, which is used for
HVAC and fan applications. For Constant Torque Mode, which is desirable for most machine
applications, set Jumper J10 to the "CT" position. See Figure 22.
10.10
– JUMPER J11
Factory use only.
10.11
– SWITCHING FREQUENCY AND GFCI SELECTION (J12)
Jumper J12 is factory set to the "8K" position for a switching frequency at the motor of 8 kHz.
For 12 kHz switching frequency, set Jumper J12 to the "12K" position. This jumper also allows
the drive to be used on standard ("G1" position) or sensitive ("G2" position) GFCIs. See Figure
23. GFCI operation may increase audible motor noise.

DRIVE OPERATION
11.1
– START-UP PROCEDURE
After the drive has been properly setup (jumpers and trimpots set to the desired positions) and wiring completed, the start-up procedure can
begin. If the AC power has been properly brought to the drive, the power (PWR) LED will illuminate green. The status (ST) LED will indicate
drive status, as described in Section 13.2 on page 18. When the drive is started, the motor will begin to accelerate to the set speed.
WARNING!
Using a jumper to eliminate the start/stop function will cause the motor to run at the Main Speed Potentiometer setting when
the AC Line is applied.
Note: If the motor rotates in the incorrect direction, it will be necessary to disconnect the AC Line, reverse any two motor leads, and repeat the
start-up procedure.
11.2
– RESTARTING THE DRIVE AFTER A FAULT HAS CLEARED
1,2
The drive monitors five faults: Undervoltage, Overvoltage, Short Circuit at the motor (phase-to-phase), Overload and Phase Loss Detection. See
Section 13.2 on page 18 for the Status (ST) LED indication. See Section 10.3 on page 15 for Automatic Ride-Through or Manual Restart
selection with Jumper J3. The drive can be restarted (after the fault has been cleared) by disconnecting the AC power, and all LEDs are no
longer illuminated, and then reconnecting the AC power.
Notes: 1. For an Overload Fault, be sure the fault has been cleared before restarting the drive. Check the motor current with an AC RMS
responding ammeter. Also, the CL setting may be set too low. See Section 12.7 on page 17. 2. For an Overvoltage Fault, if the drive is set for
Automatic Ride-Through, the drive will automatically restart when the AC Line voltage returns to below the specified Overvoltage Trip Point.
