11 Precautions for Using the MP230011.1.1 Parameters Updated when a MECHATROLINK Connection Is Established (1) (User Constants Self-Writing Function Enabled)11-211.1 Parameters That Are Automatically UpdatedSome of the parameters stored in SERVOPACK RAM may be overwritten automatically undercertain conditions or as a result of self-configuration. This includes MP2300 setting parameters andfixed parameters, as well as fixed value SERVOPACK parameters. Some SERVOPACK parametersare also written to setting parameters automatically during self-configuration. The parameters thatare updated automatically under specific conditions are listed in the following tables. Refer to Chapter 6 Motion Parameters for details on MP2300 parameters. Refer to yourSERVOPACK manual for details on SERVOPACK parameters.11.1.1 Parameters Updated when a MECHATROLINK Connection Is Established (1)(User Constants Self-Writing Function Enabled)The MP2300 parameter settings in the left table below are automatically written to the SERVOPACKparameters given in the right table below when a connection is established between the MP2300 andthe SERVOPACK. This occurs after power is turned ON or alarms are cleared following acommunication interruption. The parameters are written only when automatic updating of parametersis enabled when bit A of fixed parameter 1 in the MP2300 is set to 0.MP2300 SERVOPACK Parameter RemarksSGD-N, SGDB-N NS100 NS115 SGDSSetting parametersPosition Completed Width OL1E → − − Pn500* Pn522** Settings arewritten only whenusing aMECHATROLINK-II operating at 10Mbps in 32-bytemode.Position Loop Gain OW2E → − − Pn102*Speed Loop Gain OW2F → − − Pn100*Speed Feed ForwardCompensation OW30 → − − Pn109*Position Loop IntegrationTime Constant OW32 → − − Pn11F*Speed Loop IntegrationTime Constant OW34 → − − Pn101*Linear Acceleration Time OL36 → Cn-0020 Pn80B −Linear Deceleration Time OL38 → − Pn80E −S-curve AccelerationTime OW3A → Cn-0026 Pn812 −Filter Type OW03Bits 8 to B → Settings are automatically enabled only when using MECHATROLINK-IIoperating at 10 Mbps in 32-byte mode.
