Parameter Details1111.7 F: OptionsYASKAWA ELECTRIC SIEP C710617 01B YASKAWA AC Drive GA700 Technical Manual 715■ F1-13: Encoder 1 Gear Teeth 2No.(Hex.) Name Description Default Setting(Range)F1-13(038C)PG 1 Gear Teeth 2Sets the number of gear teeth (gear ratio) between the motor and encoder, incombination with F1-12 [PG 1 Gear Teeth 1]. Parameter F1-13 is set withthe number of gear teeth for the load side.0(0 - 1000)The drive calculates the motor speed using the following expression when the number of gear teeth is set.Note:The gear ratio is 1 when F1-12 = 0 or F1-13 = 0.■ F1-14: Encoder Open-Circuit Detect TimeNo.(Hex.) Name Description Default Setting(Range)F1-14(038D)PG Open-CircuitDetection Time Sets the detection time for PGo [PG Disconnect].2.0 s(0.0 - 10.0 s)A PGo is triggered when the drive does not detect output pulses from the encoder for longer than the time set inF1-14.Note:Faults such as ov [DB Bus Overvoltage] and oC [Overcurrent] may occur depending on the motor speed and load conditions.■ F1-18: Deviation 3 Detection SelectionNo.(Hex.) Name Description Default Setting(Range)F1-18(03AD)Deviation 3 DetectionSelection Sets the number of rotations to detect scenarios in which the torquereference and rate of acceleration are inverted, which function as thedetection conditions for dv3 [Inversion Detection].10(0 - 10)A dv3 is triggered when the following two conditions are detected simultaneously for the number of times set forF1-18.• The torque reference and acceleration are in opposite directions. (for example, torque reference is in forward runand the acceleration is in a negative direction)• Difference between the speed reference and the actual motor speed is greater than 30%.Note:• Reference the setting value for E5-11 [Encoder Z-Pulse Offset] and the δθ value found on the motor nameplate. A common cause for adv3 fault is the incorrect setting of E5-11.• This function is disabled when F1-18 = 0.■ F1-19: Deviation 4 Detection SelectionNo.(Hex.) Name Description Default Setting(Range)F1-19(03AE)Deviation 4 DetectionSelection Sets the number of pulses used to detect dv4 [Inversion PreventionDetection].128(0 - 5000)A dv4 [Inversion Prevention Detection] is triggered when the pulses in a reverse direction to the speed referenceare input for longer than the time set in F1-19.Note:• Reference the value set in E5-11 [Encoder Z-Pulse Offset] and the δθ value found on the motor nameplate. A common cause for a dv4fault is the incorrect setting of E5-11.• Set F1-19 = 0 when using a drive in an application in which the motor is rotated from the load side in the direction reverse to the speedreference.V/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLVV/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLVV/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLVV/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLV
