To eliminate the Start/Stop function, hardwire Termi-
nals RUN and COM with the jumper that is provided.
Be sure Jumper J9 is set to the “NO” position. See
Figure 16.
WARNING! Using a jumper to eliminate the
Start/Stop function will cause the motor
to run at the Main Speed Potentiometer setting
when the AC Line is applied.
5.7 Voltage Following Connection – An isolated*
0 – 5 Volt DC analog signal input can also be used
to control motor speed in lieu of the Main Speed
Potentiometer. The drive output will linearly follow
the analog signal input. Wire the signal input posi-
tive lead (+) to Terminal P2 and the negative lead (-)
to Terminal P1. With
external circuitry, a
0 – 10 Volt DC analog
signal can also be used.
See Figure 17.
*If a non-isolated signal
is used, install the
SIAC-PS Signal Isolator
with Power Supply . The
SIAC-PS accepts voltage
(0 to ±2.5 thru 0 to ±25
Volts DC) or current
(4 – 20 mA DC) signal
inputs. See Table 2 on
page 9. See Appendix A
on page 33 for SIAC-PS information.
Note:
For signal following
operation, the Minimum Speed
Trimpot (MIN) must be set fully
counterclockwise.
WARNING! The signal input
must be isolated from
the AC Line. Earth grounding
signal wiring will damage the
drive and void the warranty.
It is highly recommended that
the SIAC-PS Signal Isolator with
Power Supply be installed when
using signal following.
5.8 Enable Circuit Connection –
The drive can also be started and stopped with an Enable circuit (close to run, open to stop).
See Figure 18.
The Enable function is established by wiring a switch or contact in series with the orange Main
Speed Potentiometer lead which connects to Terminal P2. When the Enable Switch is closed, the
motor will accelerate to the Main Speed Potentiometer setting. When the Enable Switch is opened,
the motor will decelerate to stop.
WARNING! If the Enable Switch is to be mounted remotely, it is highly recommended that the
SIAC-PS Signal Isolator with Power Supply be installed.
