P70 [Anlg in1 Sel] = Speed Ref A
P71 [Anlg In1 Cfg] = +/- 10
Note: DIP switch S9 should be
set to “On”

(1) Require for initial startup and operational
checks. Voltage must be present at these points
during operation. In other words, these
terminals must be made. If open, the drive will
be ‘Not Ready’.
(2) RUN – Edge sensitive signal that initiates a
Run command (0 1 = Run). If the Drive is
Run, voltage may be applied to the armature
causing the motor to reach the desired speed.
The Run input is latched and therefore does not
have to be maintained to keep the drive
Running.
