When power is connected, the ACS 140 will automatically check for the presence of the panel. If the panel is detected, the ACS 140 will set up the Modbus communication using the default settings shown in Table 2. This communication setting is then used until the next power down. If the panel (or any other master that uses communication setting shown in Table 2) is NOT detected in 4 seconds after power up, the ACS 140 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 140 (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 ACS 100 - PAN control panel is not connected when the power is applied.

For details, see the ACS 140 Programming Guide. General When the ACS 100 - PAN control panel is attached to the drive, the panel communicates using the Modbus protocol and the settings given in Table 2. When power is connected, the ACS 140 will automatically check for the presence of the panel. If the panel is detected, the ACS 140 will set up the Modbus communication using the default settings shown in Table 2. Thissettings of the ACS 140 can be
