PG SYSTEMS OF INVERTER


PG CONSTANT .

To set the pulse number of generator or encoder when pg is used
note:to set the pulse number of generator or encoder when pg is used. the unit s p/r  . set the number of phase a or phase b pulse s in one motor revolution.

OPERATION SELECTION AT PG OPEN CIRCUIT .

This constant sets the stopping method that is used when the signal from the pg is lost. 0: deceleration to stop using deceleration time 1( c 1-0 2). 1: cost to stop  . 2: emergency stop using the emergency stop time (c 1- 0 9). 3:continue operation ( display :P G O: and continue operation with v/f control.
note: please set the detection time when pg signal wire is disconnected and the stop method sifter the signal wire loss is detected


PG ROTATION .
To set  the pg rotation direction . 0:phase a leads with forward run  command  (please b leads with reverse run command ) 1: phase b leads with forward run command .(phase a leads with reverse run command ).
note : this constant is used to coordinate the pg ,s rotation direction with the motor,s rotation direction generally direction (looking from the input axis ). when a forward reference is output the motor rotation in the counterclockwise direction ( looking from the input axis ).when the motor is in forward rotation please set pg ,s output is phase a leas or phase b leads.

PG DIVISION RATE ( PG PULSE MONITOR ).
Sets the division ratio for the pg speed control card pulse output .
note : this constant is only effective when a pg-b2 is used it sets the division ratio used when the pulse monitor output is connected to a pulse input device . the first digit in the setting (0 or 1) is n and the second two digits ( 01 to 32 ) are m . the division ratio is calculated from n and m with the following equation , division ratio = (1+n )/m setting range n:0, 1m :1 to 32. possible division rate settings are as follows :1/32<f1 -06 <1. for example , if the division rate is :1/2 (a setting of ,2, ),the monitor output will be falf of the number of pulse output from the pg .
