Application macros and wiring
13. E-bypass (USA only)
This application macro is intended to be used with an electronic
bypass device, which can be employed to bypass the drive and
connect the motor directly on-line.
When using a direct speed reference in the AUTO mode, the
speed reference must be connected to analogue input 1 (AI1)
and the START command is given with digital input 1 (DI1). In
the HAND/OFF mode, the speed reference and START
command are given through the control panel (operator keypad).
If process PI(D) is used, the feedback signal must be connected
to analogue input 2 (AI2). By default, the setpoint is set from the
control panel, but it can also be changed to analogue input 1.
Process PI(D) must be commissioned and adjusted with
parameters (
Group 40: PROCESS PID SET 1
) or using the PID
control assistant (recommended).
