INVERTER,S NUMBER OF PG GEAR TEETH 1 / 2 AND PG OPEN CIRCUIT DETECTION TIME OF INVERTER .

NUMBER OF PG GEAR TEETH 1 / 2 .


To set the ratio between motor,s gear teeth number and that of pg .
note: when v / f  control with pg feedback is used , the motor can be operated even if there are gears between the motor and pg because the responsiveness is lower than it is with vector control.set the number of teeth on the gears if there are gears between the motor and pg . the motor speed will be calculated within the inverter using the following equation. motor speed  (r/min) .number  of pg pulses input from the pg x 60 number of gear teeth  2 (f1-13) number of pg pulses (f1-01)  number of gear teeth 1 (f1-12) , a gear ratio of 1 (f1-12 = f1-13 = 1) will be used if either of these constants is set to 0.

 PG OPEN CIRCUIT DETECTION TIME.

Used to set the pg disconnection detection  time . sets the functions for channel 1 to 3 which are effective when the a1-14b analog reference card is used . 0: 3-channel individual input (ch1 :terminal 36:ch2:terminal 39 : ch3: terminal 42) 3- channel additional input (sum of ch1 to ch3 is used as the frequency reference value.)
note: when using a a1-14b /a1-14u analog reference card set constant b1-01 (reference selection ) to ,3, (option). when using a a1-14b set the function for channels 1 to 3 with constant f2-01 , (there are no constants to set for a1-14u). note: constant b1-01 (reference selection ) must be set to 1 (external terminal) when 3- channel individual input ( setting:0) is set ,when using a a1-14b and setting 3- channel individual input , the multi function inputs cannot be set to the option / inverter selection function (setting: 2).
