KB Electronics Installs on end of KBVF - Manual (Page 20)

Note: A connection must be made between FWD and COM or REV and COM in order
for control to operate. Jumper shown installed in FWD direction.
See Table 2, Terminal Block Wiring Information, on page 9.
Note: The MIN and MAX trimpots on the KBVF are non-operational after the SIVF is
installed.
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.
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” termi-
nal.
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.
