Motor Speed Vs. Applied Motor Load (Torque Mode) - KB Electronics Penta Power KBRG-212D Installation And Operation Manual

In the torque control mode
(J5 set to TRQ), the
KBRG-212D will vary the
maximum motor torque as
a function of the voltage
input to terminals "SIG"
(signal) and
(common). This voltage
can be derived from the
wiper of
potentiometer or from an
analog input
following). If the motor
torque is greater than the
load torque, the motor will
rotate. If no load is
applied to the motor, the
motor will rotate at a
speed proportional to the
torque setting as set by
the main potentiometer (See Figure 13, on page 21). By using the FACC and RACC
Trimpots, the application of torque can be made more gradual or less gradual as
required by the application. A maximum torque can be established using the current
selector jumper, J2, which can be further modified by using the FCL and RCL Trimpots.

terminals "EN" and "COM" on terminal block
TB1 is opened, the control will cause the
motor to stop. When jumper J6 is in the
factory position ( RTS ), the motor will
regenerate to a stop. The stop time is
controlled by the Forward Acceleration
(FACC) and Reverse Acceleration (RACC)
Trimpots. If J6 is changed to the coast to stop
(CTS) position, the motor will coast to a stop
when the "EN" - "COM" circuit is opened. See
Figure 15.
Note: Control will not run unless a jumper or closed contact is connected between the
"EN" and "COM" terminals.
