158 ACH580 E-Clipse bypass and packaged drive user manual
Embedded fieldbus
MODBUS addressing – Bypass
0xxxx Registers
MODBUS addressing of 0xxxx registers maps the Bypass Control Word shown in
the following table to the first 16 coils when using the bypass device ID. The coil
number is the bit number plus 1. In other words, bits 0-31 are mapped to 1-32.
Relay output control is possible on the bypass by using coils 33-37 and the bypass
device ID. Relay control on the drive is described in the 0xxxx mapping subsection of
the Modbus addressing section for the drive device ID on page 139.
These registers are summarized in the following tables. Reminder: stop and enable
related bits are valid at only one device subject to the status of bypass
parameter 1625, COMM CTRL.
