6.8 Main Speed Potentiometer Connection – The main speed potentiometer can be
connected in several ways. (A 5kΩ ohm potentiometer is supplied with control. A 10K
potentiometer can also be used.) See Figures 6A – 6D.
6.8.1 Unidirectional operation (FORWARD) – Connect potentiometer to terminals
“+15,” “SIG,” “COM” for forward direction as per Figure 6A.
6.8.2 Unidirectional operation (REVERSE) – Connect potentiometer to terminals
“-15,” “SIG,” “COM” for reverse direction. As per Figure 6B.
6.8.3 Bidirectional operation using reversing contacts – Connect potentiometer
to terminals “-15,” “+15”, “SIG,” “COM” as per Figure 6C.
6.8.4 Bidirectional operation with potentiometer – Connect potentiometer to
terminals “-15,” “+15” “SIG” as per Figure 6D.
