◆ F1: Error Detection for V/f Control with PG
A one-track pulse signal can be connected to the V1000 pulse train input RP as speed
feedback. Using this signal for slip compensation improves the speed control accuracy. This
function is only available for motor 1.
The F1 parameters determine how the error detection for the speed feedback signal works.
Refer to C5: Automatic Speed Regulator (ASR) on page 86 for details how to activate ant
tune the function.
■ Operation at PG Fault Detection
The drive lets the user select from one of four possible operations when a fault occurs with
the PG encoder. The operation can be set up separately for each fault using parameters F1-
02/03/04. The table below list the stopping methods and the parameter setting values.
