－ 69 －－ 68 －CommunicationCommunicationOverview of communicationWith the upper host controller, which can be connected with 31 brushless amplifiers atthe maximum via serial communication conforming to RS485, enables the following:1. Rewriting parameters2. Browsing and clearing status and history of trip condition3. Monitoring control status including present position, status, I/O, etc.4. Start and stop of motor[Advantage]• It is allowed to write parameters by one operation from host controller in startup of themachine.• Operating condition of the machine can be displayed, which improves serviceability.Connection of communications lineConnect one host controller with more than one brushless amplifier via RS485 communi-cation, and set the device number of each brushless amplifier (Pr60) at 81h (129) to 9Fh(159). Set the device number for the host as 01h (1) to 1Fh (31).Device number is set at 81h (129) in default setting. When connecting more than onebrushless amplifier via RS485, be sure to change the device number beforehand withthe Digital key pad or communication software “PANATERM for BL” (Can be download-ed from our web site).[Example of connection]RS485Host controllerDevice number= 01h(1)Device number= 81h(129)Device number= 82h(130)Brushless amplifierDevice number= 83h(131)Device number= 84h(132)...
