F. Voltage Following – An isolated FIG. 14 – VOLTAGE analog voltage can be used in lieu FOLLOWING CONNECTION of main speed potentiometer. Connect signal to terminals “SIG" and “COM.” Note: Terminal “COM" is common. A positive signal to terminal “SIG” will produce a positive output to motor. A negative signal to terminal Jumper* “SIG" will produce a negative 0 – ±10V VDC output. A 0 to ±10VDC is required to operate control from 0 ± full output. Note: Jumper J4 must be in the “10V” position.
i. Regen to a stop using terminals EN and COM on terminal block TB1 – When a contact is opened between terminals “EN” and “COM,” with jumper J6 in the “RTS” position, the motor will regeneratively brake to a rapid stop. Application note (See fig. 15): If controlled regen to stop is required, a contact can be installed in series with the signal “SIG” connection.
H. Tach-generator Feedback – The KBMG212D is factory set for armature feedback, which provides good load regulation for most applications. For superior load regulation, analog tach-generator feedback can be used. FIG. 17 – TACH-GENERATOR FEEDBACK Wire the tach-generator so that the polarity of the tach-generator is the same with respect to the input signal polarity (see fig. 17). Note: If tach-generator is wired with reverse polarity, the motor will run at full speed.

The KBMG-212D contains trimpots that have been factory adjusted for most applications. See specifications for factory settings. (Note: Fig. 12, p. 20, presents the various trimpots with their location.
A. Forward Acceleration (FWD ACCEL) and Reverse Acceleration (REV ACCEL) – The FWD ACCEL trimpot determines the amount of time it takes the control voltage to reach full output in the forward direction. It also determines the amount of time it takes for the control voltage, in the reverse direction, to reach zero output. (FWD ACCEL is the Reverse Decel.) FIG. 18 – ACCEL TRIMPOT ADJUSTMENT 100 (%) SPEED ACCEL TRIMPOT SETTING 7.5 1.0 14.0 0.1 15.
Note: A 4-quadrant ACCEL/DECEL accessory module (KB P/N 8834) is available as an option. It provides separate control of FORWARD acceleration and deceleration and REVERSE acceleration and deceleration. B. Dead Band Trimpot (DB) – The DB trimpot sets the amount of main speed potentiometer rotation or analog voltage input required to initiate control voltage output. It is factory adjusted to approximately 25% of rotation. FIG.
iii. Adjust DB trimpot CW until motor hum is eliminated. (See fig. 19, p. 27 for graphic illustration of the DB trimpot.) Note: If the dead band trimpot is set too low (CCW direction), the motor may oscillate between forward and reverse. Adjust dead band trimpot CW until the instability disappears. (Oscillation may also occur due to RESP and IR COMP trimpot settings. See sec. VII, D & F on page 29.) C.
