Adjusting Frequency Reference Using Pulse Train Inputs - YASKAWA varispeed G7 CIMR-G7B series Instruction Manual

Adjusting Frequency Reference Using Pulse Train Inputs

The frequency reference can be adjusted when b1-01 (Reference Selection) is set to 4 (Pulse Train Input). Set
the pulse frequency in constant H6-02 to 100% reference, and then adjust the gain and bias accordingly using
H6-03 and H6-04.
