With the Altistart 48 using Modbus, the manual for the soft starter shows parameter PCt in the COP menu as off for normal control or serial com. The manual for modbus shows parameter PCT (word 2294) exactly opposite. Which is correct?
The default setting on the keypad for PCT is off. This is the setting that will allow Modbus control or terminal control. On, is for powersuite control or keypad command. It is not necessary to change word 2294 to allow serial communication control. The error is in the modbus manual.
