Connect HI SPEED POT 1 to HI SPEED POT 2 by placing posi-
tion 3 of switch S1 in the “on” (closed) position when no external
control is required.
6.3 BASE SPEED
Base speed is the rate at which a specific motor and load will start
of stop with no acceleration or deceleration.
1. Connect BASE SPEED ONLY (J1, pin #14) to SIGNAL COM-
MON.
2. Connect RUN (J1, pin #6) to SIGNAL COMMON.
3. Turn “Base Speed Pot” (R4) clockwise to
increase
base speed.
Speed (pulse frequency) can be monitored at J-1, pin #10 (PULSE
OUT). Position 4 of switch S1 should be “on” (closed).
Three ranges of Base Speed and High Speed can be selected
with DIP switch S1 as follows.
* The maximum speed attainable by the drive is 10 kHz
The following table lists approximate settings for Base Speed Po-
tentiometer R4 when using range 2 (0 — 2500 Hz) and with High
Speed Potentiometer R3 set for 20 kHz.

6.4 HIGH SPEED
HI SPEED POTS 1 AND 2 ARE EITHER CONNECTED TO-
GETHER (FOR ON BOARD OPERATION) OR ARE CONNECTED
TO A REMOTE POTENTIOMETER. (Potentiometer set at minimum
resistance.)
1. Make sure that BASE SPEED ONLY (J1 pin #14) is
OPEN.
2. Connect RUN (J1 pin #6) to SIGNAL COMMON.
3. Turn HIGH SPEED POT (R3)
counterclockwise
to increase ve-
locity to desired maximum limit.
Speed (pulse frequency) can be monitored at J-1, pin #10 (PULSE
OUT). Position 4 of switch S1 should be “on” (closed).
The settings of “DIP” switch S1, described in 6.3, also affects the
High Speed Range as noted in 6.3.
The following table lists approximate settings for High Speed Po-
tentiometer R3 when using range 2 and with Base Speed Potenti-
ometer R4 set for 0 Hz.

NOTE: Because of the oscillator design, the high speed cannot
be set lower than the speed set on the base speed potentiom-
eter. For example, if base speed is set to 200 Hz, the high speed
can be set no lower than 200 Hz.
6.5 ACCELERATION
Acceleration time to high speed, with the Acel potentiometer (R2)
fully counterclockwise is approximately 50 milliseconds. Range is
from 50 milliseconds to 2 seconds (approximately).
