Terminal FM/AM Signal Selection
The signal type for terminals FM and AM can be set to either voltage or current output using jumper S5 on the terminal board
as explained in
Table i.15
. When changing the setting of jumper S5, parameters H4-07 and H4-08 must be set accordingly.
The default selection is voltage output for both terminals.

MEMOBUS/Modbus Termination
This drive is equipped with a built-in termination resistor for the RS-422/RS-485 communication connector. DIP switch S2
enables or disabled the termination resistor as shown in
Table i.17
. The OFF position is the default. The termination resistor
should be placed to the ON position when the drive is the last in a series of slave drives.

DANGER! Electrical Shock Hazard. Do not touch SW1 or SW2 screws while power is applied to the drive. Failure to comply will result in
death or serious injury.
WARNING! Electrical Shock Hazard. Connect the ground cable correctly. Failure to comply may result in death or serious injury.
NOTICE: When disabling the internal EMC filter, move the screws from ON to OFF and then tighten to the specified torque. Completely
removing the screws or tightening the screws to an incorrect torque may cause drive failure.
NOTICE: Keep SW1/SW2 screws positioned together (ON/ON or OFF/OFF). Screws at different positions may cause drive failure.
Note:
For floating, impedance grounded, or asymmetrically grounded networks, disconnect the internal EMC filter by moving the SW1/SW2
screws to the OFF position.
n
Asymmetrical Grounded Network
Table i.18
shows asymmetrical grounded networks. Asymmetrical networks require screws SW1 and SW2 to be in the OFF
position. The internal ground connection for the filter is removed when the screws are in the OFF position. (Drives are shipped
with SW1 and SW2 screws installed at the OFF position.)
