- Refer to the Jumper and
Adjustment Settings table in the 1397 User Manual, Publication 1397-um000 for additional details. (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.
