Page 7: Setting Mode Of Drive (Speed Or Torque Control)
SETTING MODE OF DRIVE (SPEED OR TORQUE CONTROL). The KBRG-255 can be operated as a speed control or torque control by setting the position of jumper J7. The main speed potentiometer controls the magnitude of the mode selected. Set jumper J7 to "SPD" for speed control or to "TRQ" for torque control. (See fig. 1, p. 3.) A. -

Page 9: Mounting
For example, if the tach is 25V/KRPM and the motor speed is 3,600 RPM, use the "50V" J4 position. For other tach-generator voltages and motor speeds, an external resistor (RT) may be used as follows. Install resistor in series with either tach-generator lead. Place J4 in "7V"... -

Page 14: Viii. Trimpot Adjustments
VIII. TRIMPOT ADJUSTMENTS. The KBRG-255 contains many trimpots which have been factory adjusted for most applications. (See table 2, p. 2. for factory settings.) (Note: fig. 1, p. 3 presents the various trimpots with their locations. They are shown in the approximate adjustment position.) Some applications may require readjustment of trimpots in order to tailor control to exact requirements. - Page 15 C. Deadband (DB) – The DB trimpot sets the amount of main speed potentiometer rotation required to initiate control voltage output. It is factory adjusted to approximately 25% of rotation. The DB trimpot also determines the amount of delay that will occur before regeneration starts.

G. Response (RESP) Trimpot – This trimpot determines the dynamic response of the control. The factory setting is approximately 50% of full rotation. The setting may be increased if a faster response is required. (Note: If response is made too fast, unstable operation may result.) H. -
