5-95.2.5 Mechanical Setting ModeThis is a special mode for changing parameters related to the mechanical settings. Parameters #200 to #299 canbe changed only when this operation is being executed. In addition, once started, this operation cannot bestopped. After you finish changing the necessary parameters, turn the power to the driver off and on again.Note that if you change these parameters, the changed values are not reflected until after the power is turned onagain. Therefore, please note that if you try to read a parameter value after you change the parameter, the valuebefore the change is read until you turn the power off and on again.5.3 Coordinate System5.3.1 Coordinate SystemThe driver controls the position of the motor by three coordinate systems with different units: a command unitcoordinate system, and a pulse coordinate system.The pulse coordinate system manages the coordinate values in units of pulses that can be detected by the encoderresolver. The position control part of the driver controls the motor based on these coordinate values. It has acommand value and a current value, and they are always updated and displayed in the #320 Pulse positioncommand value monitor and #321 Pulse position current value monitor, respectively.The command unit coordinate system manages coordinate values in the amount of pulses on the controllerinterface. The position command values that occur in the driver itself (test operation, auto-tuning operation,homing operation, jog move operation) are also processed based on these coordinate values. The command unitcoordinate system has command values and current values, each of which are constantly updated and displayedin the #323 Command unit command value monitor and the #370 Command unit current value monitor,respectively.5.3.2 Switching Position Command Pulse WeightsThe position command value instructed from the controller interface is given to the driver by any pair of the(PLS, SIGN), (UP, DOWN) and (A, B) signals, which is then reflected in the command unit command value.Normally, the pulse position command value inside the driver for a single pulse on the controller interfacebecomes the value set with the #207 Simplified scaling weighted data parameter. For example, if the settingvalue is 4, a single pulse on the controller interface will be equivalent to 4 pulses inside the driver.In addition, the command unit current value is output from the driver by either the (UP, DOWN) or (A, B) signal.The pulse position current value inside the driver for a single pulse on the controller interface always becomesthe value set with the #207 Simplified scaling weighted data parameter. For example, if the setting value is 4,a single pulse on the controller interface will be equivalent to 4 pulses inside the driver.While the input signal ìPLS_DIRECTî is on, the position command value instructed from the controllerinterface is independent of the value set with the #207 Simplified scaling weighted data parameter; a singlepulse on the controller interface will be a single pulse inside the driver, instead. However, do not change thestatus of any of the (PLS, SIGN), (UP, DOWN) and (A, B) signals for 2 msec each before and after switching theinput signal ìPLS_DIRECTî (off → on, on → off).[Related parameters]#207 Simplified scaling weighted data5
