*Note: Remove factory jumper from J2-8 and J3-24 before connecting switch at J2-8.
See recommended tightening torques in Table A-2.
See Figure 5-4 for connection information.
The Parameter Dec Value column can be used when entering the PLC conguration parameters at the keypad (parameters
are shown as decimal long values - byte3.byte2.byte1.byte0).
For this mode Enable is active.
Use of logical variables A, B, C or D allows for complex PLC logic.
Variable “A” is set based on the outcome of a comparator and then used as an input condition for the torque/speed select
and PID actions.
