Figure 4.4.31 Speed follower from external PG
Parameter settings:
1. Frequency reference selection: 00-05=4 (Pulse input)
2. Pulse input’s function selection: 03-30=0 (General pulse input)
3. Pulse input scale: 03-31 (set the number of pulse in Hz to match maximum output frequency, 01-02)
4. Pulse input gain: 03-32 (Set the input gain of the pulse frequency set by 03-31
5. Pulse input bias: 03-33 (Set the input bias of the pulse frequency set by 03-31)
6. Pulse input’s filter time: 03-34 (if the pulse input is unstable due to the interference, increase value.)
Use the forward and reverse multi-function inputs to choose motor direction.
Note: For higher accuracy use PG feedback in SV or V / f + PG control mode.
