Chapter 3 – Programming
This chapter describes how to program the ACS 160 drive for Modbus
communication.The reader should be already familiar with programming the
drive parameters using the control panel, and the way the parameters are
arranged in groups. For details, see the ACS 160 User’s Manual.
General
When power is connected, the ACS 160 will automatically check for the
presence of the panel.
If the panel is NOT detected in 7 seconds after power up, the ACS 160 will set
up Modbus communication normally, using the parameters 5201
STATION ID,
5202
COMM SPEED and 5203 PARITY. This communication setting is then used
until the next power-down.
Note! If any of the parameters 5201 STATION ID, 5202 COMM SPEED and 5203
PARITY has been altered, the control panel will operate only if it is connected
before the power is applied to the ACS 160 (or immediately after power-up).
Note! If any of the parameters 5201
STATION ID, 5202 COMM SPEED and 5203
PARITY is altered, the modification takes effect only on the next power-up, and if
the control panel is not connected when the power is applied.
