Multi - Drop - Applications
This mode is available setting DIP-switch no. 10 at the front panel of the drive to ON. The wiring
principle for multi-drop applications is shown below. Each connected drive will also get it´s own
hardware address. The setting can be done by DIP-switches AS1-4 on the front panel or by using
the setup software Work Bench v5.
The picture below shows termination resistors on the last connected drive. The resistor can be
activated by using DIP-switch AS1.6 and set it to ON-position.
