Chapter 7 Servo ParametersRevision June 2010 7-35Display Format: DecimalSettings:This parameter is used to set the denominator of the electronic gear ratio. Thenumerator of the electronic gear ratio is set by P1-44. P2-60 ~ P2-62 are used toset the additional numberators.As the wrong setting may cause motor to run chaotically (out of control) and it maylead to personnel injury, therefore, ensure to observe the following rule whensetting P1-44, P1-45.The electronic gear ratio setting (Please also see P1-44, P2-60 ~ P2-62):f1 f2 = f1 x NMNMPulse input PositioncommandThe electronic gear ratio setting range must be within: 1/50Please note:1. In PT r mode, the setting value of P1-45 can not be changed when the servodrive is enabled (Servo On).P1 - 46▲ GR3 Encoder Output Pulse Number Address: 015CH, 015DHDefault: 2500 Related Section: N/AApplicable Control Mode: ALLUnit: pulseRange: 20 ~ 40000Data Size: 32-bitDisplay Format: DecimalSettings:This parameter is used to set the pulse numbers of encoder outputs per motorrevolution.Please note:When the following conditions occur, the output frequency for pulse output mayexceed the specification and cause that the servo drive fault AL018 (EncoderOutput Error) is activated.Condition 1: Encoder error.Condition 2: Motor speed is above the value set by parameter P1-76.f1: Pulse input f2: Position commandN: Numerator, the setting value of P1-44 orP2-60 ~ P2-62M: Denominator, the setting value of P1-45
