Connecting the control signal terminals
The control signal terminals are arranged in a single row.
Wire the control signal terminals to suit their application. For
instructions for changing the function of the control signal
terminals, see paragraph “Control signal terminal overview
(input)”, page 74.
Use twisted or screened cables for connecting to the control signal
terminals. Earth the screen on one side with a large contact area
near the frequency inverter. The cable length should not exceed
20 m. For longer cables, use a suitable signal amplifier.
The illustration to the right shows the positions of the individual
control signal terminals.
Table 9: Connection options for control signal terminals
If the use of ferrules is required, use only ferrules with push-on
sleeves.
Caution!
Never connect terminal P24 with terminals L, H, O, OI or
AM.
ESD measures
Discharge yourself on an earthed surface before touching
the control signal terminals and the circuit board to
prevent damage through electrostatic discharge.
