DRIVE SETUP AND ADJUSTMENT
49’1340 e FlexPak 3000 4-5
4.5.5 Field Supply Jumper Connection (FIELD SUPPLY) - J21 Jumper
NOTE: This jumper has no affect on the standard field supply or the field current regulator.
The FIELD SUPPLY jumper (J21) determines the voltage range that the drive expects to see
from the optional Field voltage controller kit. Refer to I/M 49’1344 for more information on that
kit. The position of this jumper must correspond with the voltage range selected via the jumper
wire on the optional Field voltage controller.
Jumper Connection D-C Field Voltage Range (1)
B-C 45% of VAC to 90% of VAC
(1) VAC is the RMS Line to Line Voltage at 3V and 3W.
4.5.6 Setting the Source for the Manual Mode Reference (MANUAL REF) - J19 Jumper
CAUTION: The drive will not run at the correct speed if this jumper is not set to the correct position.
Failure to observe this precaution could result in damage to, or destruction of, the equipment.
The MANUAL REF jumper (J19) determines whether the internal +10 V isolated power supply
or an external +10 V source is used for the manual mode reference.
To use the +10V power supply for the manual reference potentiometer, place the jumper on
pins 2 and 3 (POT). The supply at terminal 16 of the regulator board terminal strip is used.
To use an external +10 V source, place the jumper on pins 1 and 2 (EXT). The external
reference is connected at terminals 17 and 18 of the regulator board terminal strip.
NOTE: This input can be used as a trim on auto mode speed reference by setting the jumper
on pins 1 and 2 (EXT). In this case a
± 10 V reference can be used.
4.5.7 Setting the Tachometer Voltage Range (TACH V RANGE) - J14 Jumper / and
Tachometer Voltage Scale (TACH V SCALE) - J11 Jumper
The TACH V RANGE (J14) and TACH V SCALE (J11) jumpers set the voltage range and scale
of the analog tachometer.
NOTE: This jumper is ignored if an analog tachometer is not used and if FEEDBACK SELECT
is not set to DC TACH or AC TACH.
CAUTION: The drive will not run at the correct speed if these jumpers are not set to the correct
position. Failure to observe this precaution could result in damage to, or destruction of the equipment.
During "Quick Start", the drive calculates the value of the tachometer range based on the
values of TOP SPEED and ANLG TACH VOLTS/1000 and the setting of FEEDBACK SELECT.
The correct values are displayed on the Correct Scaling Jumper Positions screen.
Verify these settings prior to performing the Self Tuning procedure.
The expected analog tachometer voltage range can be set to a maximum of 250 or 62 VDC.
J11 selects the hardware circuitry to maximize the resolution over the entire speed range.
Jumper J14 Jumper J11
Top Speed Tach Volts < 16 volts LOW 16
Top Speed Tach Volts < 31 volts LOW 31/125
Top Speed Tach Volts < 62 volts LOW 62/250
Top Speed Tach Volts < 125 volts HIGH 31/125
Top Speed Tach Volts < 250 volts HIGH 62/250
NOTE: The output voltage of the tachometer must not exceed 250 V for DC tachometers or 275
RMS for AC tachometers when the motor is rotating at TOP SPEED. To calculate the output
voltage at top speed, multiply the two parameter values:
Tachometer Voltage at TOP SPEED = TOP SPEED x ANALOG TACH VOLTS
