47Enter in LF.27 the pulses per revolution of the encoder, i.e. 1024, 2048, 4096etc.LF.28 can be used to swap the encoder channels such that the encoder isincrementally counting in the same direction as the motor. Initially leave thisparameter set to 0 or no reversal. Whether or not reversal is necessary willbe determined later in section 5.11.2LF.29 sets the sample time for the speed measurement. Initially the defaultsetting of 4 mSec will work fine.Set up of the encoder is complete!The speed and torque controller are adjusted in parameters LF.30 throughLF.36. For initial start up the default settings will work. Once the elevator isrunning at high speed, it might be necessary to come back to adjustLF.31...LF.33. LF.34 and 35 are adjusted automatically by the drive and shouldrequire no adjustment by the user.LF.30 is the one parameter which will need to be adjusted for initial operation.If operating open loop set LF.30 = 0 and if operation is closed loop speed ortorque control initially set LF.30 = 2. Once the proper direction of rotation isestablished LF.30 can be changed to a value of 4 if torque control is ultimatelydesired.Set up of the controller is complete!The speeds are adjusted through parameters LF.41...LF.45. The profile isadjusted through parameters LF.50...LF.53.When operating with digital speed selection and control, each speed mustbe adjusted respectively.LF.41 = Leveling speed LF.42 = High speedLF.43 = Inspection speed LF.44 = high leveling speedLF.45 = intermediate speedThe default settings for the profile parameters LF.50...LF.53 are a good placeto start. When operating with analog speed or torque control, only high speedmust be adjusted to the contract speed value. In addition the profileparameters must be adjusted such that the internal ramp generator in thedrive is disabled. This can be done with the following settings:LF.50 Start Jerk = 32 ft/sec3 LF.51 Acceleration = 12 ft/sec2LF.52 Decel Jerk = 32 ft/sec3 LF.53 Deceleration = 12 ft/sec 2Set up of the speeds and profiles are complete!5.9 ControllerSettings5.10 Speed andProfile SettingsInitial Start Up
