－ 83 －－ 82 －• $S: Parameter writing command (with EEPROM writing function)Received data (Host → Amplifier)SOH STX $ S 8 0 P1 P2 P3 P4 ETX BCCAmplifier ID Host ID Command Parameter address Parameter value• When the device number set on the amplifier (value of Pr60) matches with theamplifier ID of received data, parameter change is executed.• When parameter address and parameter value are abnormal, NAK is answered.• Set the parameter address at ‘80 □□ ’. (‘8062’ for Pr62)• Set the parameter value in 4 digits of ASCII code (P1, P2, P3, and P4) which isobtained by conversion from the data to hexadecimal.(e.g. 100 = ‘0064’, –100 = ‘FF9C’)• NAK is answered while the amplifier detects undervoltage error, and the parameter isnot changed.• Changed parameter is written to EEPROM by this command. Response may takesome time since EEPROM writing process is required.• When run command is executed by I/O while parameter is being written bycommunication at the same time, enter the run command after receiving ACKresponse from the amplifier. The motor runs per the written parameter.• Writing to EEPROM should be requisite minimum.• $R: Parameter reading request commandReceived data (Host → Amplifier)SOH STX $ R 8 0 0 0 0 0 ETX BCCAmplifier ID Host ID Command Parameter address Parameter value• Set the parameter address at ‘80 □□ ’. (‘8062’ for Pr62). Set the parameter value at‘0000’.• Enter request for sending after execution of this command, parameter value isresponded.• #R: Parameter response commandTransmission data (Amplifier → Host)SOH STX # R 8 0 P1 P2 P3 P4 ETX BCCHost ID Amplifier ID Command Parameter address Parameter value• When requested parameter address is abnormal, ‘0000’ as parameter value isanswered. You should check parameter address as you requested.• When the parameter reading request command is normally completed, the amplifieranswers a parameter value when it receives request for sending.• Parameter address which is read out is sent by ‘80 □□ ’.• Parameter value is sent in 4 digits of ASCII code (P1, P2, P3, and P4) which isobtained by conversion from the data to hexadecimal.(e.g. 100 = ‘0064’, –100 = ‘FF9C’)Communication8103h: Amplifier status• $R: Status reading request commandReceived data (Host → Amplifier)SOH STX $ R 8 1 0 3 0 0 0 0 ETX BCCAmplifier ID Host ID Command Data number Data value• Enter request for sending after execution of this command, the amplifier status isanswered.• Set ‘0000’ in data value.• #R: Status response commandTransmission data (Amplifier → Host)SOH STX # R 8 1 0 3 D1 D2 D3 D4 ETX BCCHost ID Amplifier ID Command Data number Data value• When the amplifier receives request for sending after normal completion of statusreading request command, the amplifier answers status value.• #C: Data updating request commandTransmission data (Amplifier → Host)SOH STX # C 8 1 0 3 D1 D2 D3 D4 ETX BCCHost ID Amplifier ID Command Data number Data value• The amplifier saves the status in executing request for sending, and makes theresponse above when the status in receiving the next request for sending haschanged. Read data is the same as in execution of data number 8103.[Detail of status]Bit 3 Bit 2 Bit 1 Bit 0D1 0 0 0 0D2 0 0 0 0D3 Torque under restriction Overload detection 0 0D4 Homing completion In-motion In-position Trip outputDetail above is converted into hexadecimal and represented in ASCII code.e.g.) Data value = 30h 30h 30h 41h = ‘000A’ = indicates in-position status with homingcompleted.
