TRIMPOT ADJUSTMENTS

TRIMPOT ADJUSTMENTSTRIMPOT ADJUSTMENTS

The SIVFR contains multi-turn trimpots which are factory set for most applications. See Figure 1, on page 1, for the location of the trimpots.

The SIVFR is factory set for Voltage Following Operation to run the motor from zero speed to full speed with a 0 to ±5 Volt DC analog signal input. For Current Following Operation (4 – 20 mA DC), see Section 3.2.

Some applications may require readjustment of the trimpots in order to tailor the drive for a specific application. The trimpots may be readjusted as described below.

WARNING! If possible, do not adjust trimpots with the main power applied. If adjustments are made with the main power applied, an insulated adjustment tool must be used and safety glasses must be worn. High voltage exists in this drive. Fire and/or electrocution can result if caution is not exercised. Safety Warning, on page 1 of the SIVF manual, must be read and understood before proceeding.

3.1 MAXIMUM SPEED (MAX): The MAX Trimpot is factory set to run the motor at full speed with a ±5 Volt DC analog signal input. For

a higher analog signal input (±25 Volt DC max.) rotate the MAX Trimpot counterclockwise. For a lower analog signal input (±2.5 Volt DC min.) rotate the MAX Trimpot clockwise. See Figure 15.

Note: The MAX Trimpot on the KBVF has been factory set to an Upper Frequency Limit of 60 Hz (50 Hz, for 50 Hz motors). If the application requires a slightly higher maximum frequency (up to 66 Hz), rotate the MAX Trimpot on the KBVF to full clockwise position.

3.2 SIGNAL OFFSET (OFFSET): The OFFSET Trimpot is used to recalibrate the drive for Current Following Operation. The SIVFR will

run the motor from zero speed to full speed with a 4 – 20 mA DC analog signal input. For a higher minimum speed setting, rotate the OFFSET trimpot clockwise. For a lower minimum speed setting rotate the OFFSET Trimpot counterclockwise. See Figure 16.

Note: The MIN Trimpot on the KBVF is not functional when the SIVFR is installed.

The SIVF is used to isolate, amplify, and condition DC voltage and current signals from any source (power supplies, motors, tachometer generators, transducers, and potentiometers). The isolated output voltage of the SIVF provides input signals to all models of the KBVF Adjustable Frequency Drive (P/N 9957, 9958, 9959, 9977, 9978, and 9979). Signal input and motor direction control is performed by making connections to the on-board barrier terminal. All inputs (+5V, SIG, COM, FWD & REV) to the SIVF are isolated from the AC line and motor connections.

The SIVF is factory calibrated to accept signal input voltage (0 – 5V DC), current (4 – 20mA DC), or a potentiometer (5KΩ) via a jumper selection. MIN and MAX trimpots are provided in order to readjust the SIVF. This allows the use of 0 – 2.5 thru 25V DC input voltage signals for customizing specific applications.

A. Signal Following

In this mode, a signal source is used to vary motor speed. i. Voltage Following – Uses a voltage

source to vary motor speed.

Figure 5 – Voltage Following Connection

(Jumper J1 in “VOLT” Position)

Set J1 to “VOLT” position and connect the voltage source to TB1 terminals SIG (+) and COM (-). See figure 5, Voltage Following Connection. Be sure the posi- tive (+) signal is connected to “SIG” terminal and the negative (-) is connected to the “COM” terminal.

When a 0V DC signal is applied, the motor will operate at the minimum set speed (set by the MIN trimpot on the SIVF). When a 5V DC signal is applied, the motor will operate at the maximum set speed (set by the MAX trimpot on the SIVF).

ii. Current Following – Uses a current source to vary motor speed.

Set J1 to “CUR” position and connect the current source to TB1 terminals SIG (+) and COM (-). See figure 7, Current Following Connection, on page 11.

Be sure the positive (+) signal is

Figure 6 – Current Following Connection

connected to “SIG” terminal and the negative (-) is connected to the “COM” terminal.

When a 4mA DC signal is applied, the motor will operate at the minimum set speed (set by the MIN trimpot on the SIVF). When a 20mA DC signal is applied, the motor will operate at the maximum set speed (set by the MAX trimpot on the SIVF)

B. Potentiometer Operation – Uses a potentiome-

ter to vary motor speed. Set J1 to “VOLT” position and connect the 5K potentiometer

to TB1 terminals marked “SIG” (wiper of potentiometer), “+5” (high side of potentiometer), and “COM” (low side of potentiometer). See figure 7 Potentiometer Connection. When the potentiometer is set to 0% (fully counterclock- wise), the motor will operate at the minimum set speed (set by the MIN trimpot on the SIVF). When the potentiometer is set to 100% (full clockwise position) the motor will operate at full speed (set by the MAX trimpot on the SIVF).

C. Unidirectional Operation

To operate the control in forward, install a jumper between “FWD” and “COM” terminals of the SIVF

To operate the control in reverse, install a jumper between “REV” and “COM” termi-

nals of the SIVF. See figure 8, Unidirectional Operation.

Note: A SPDT switch or contact can be used as an enable to turn control on and off electronically.

Safety Warning! Do not use FWD-STOP-REV contacts as a safety disconnect since they are not fail-safe. Use only the AC line for this purpose.

D. Bidirectional Operation

i. Switch Connection –

Connect the normally open single pole double throw (SPDT) maintained switch with center off position as shown in figure 9. The center, or common terminal of the switch connects to the “COM” terminal of the SIVF and the normally open terminals of the switch connect to the “FWD” and “REV” terminals of the SIVF.

Figure 8 – Unidirectional Operation

Figure 9 – Switch Connection

(Forward-Stop-Reverse)

Making the connection between “COM” and “FWD” terminals will oper-

(Forward-Stop-Reverse)

ate the motor in the forward direction. Making the connection between the “COM” and “REV” terminals will operate the motor in the reverse direction. If no connections are made to either FWD or REV terminals, the motor will be in the STOP state. See figure 9, Switch Connections, on page 12. If the motor runs in the opposite intended direction, interchange FWD and REV connections.

Warning: Be sure to disconnect AC power, and wait until “PWR” and “ST” LEDs are no longer illuminated. HIGH VOLTAGE IS PRESENT

WHILE LEDs ARE ILLUMINATED.

ii. Open Collector Transistor Connections – Connect the open collector transis-

tor circuit as shown in figure 10. Both emitters of the transistor circuit connect to the “COM” terminal of the SIVF and the collectors of the transistor circuit connect to the “FWD” and “REV” terminals of the SIVF.

IV. CALIBRATION PROCEDURE (See Safety Warning on Page 1)

The SIVF is factory calibrated, but readjustments to the MIN and MAX trimpots can be

made to customize for a particular signal input requirement.

Note: Adjustments to the MAX trimpot will affect the MIN trimpot setting. It may be neces-

sary to repeat steps 1 through 5 to achieve accurate calibration settings. For best results, adjust MAX trimpot before adjusting MIN trimpot.

A. Calibrating the SIVF for Voltage Following (Jumper J1 in “VOLT” position):

1. Select FWD or REV direction.

2. Apply the maximum voltage input signal.

3. Monitor KBVF output and adjust the MAX trimpot on SIVF for the desired maximum setting.

4. Apply the minimum voltage input signal.
