210Dhex: ACI or AVI2 0~3FFhex or 0~1023dec
210Ehex: ACI2 or AVI3 0~FFFhex or 0~4092dec

Q How to switch between two different setpoints for PID?
A Pr00-02=9 (50Hz default)
Pr02-00=1
Pr04-19=1 and switch AVI to use ACI=AVI2 0-10V for feedback
Pr05-00=25Hz (=50% setpoint)
Pr08-00=1 (setpoint acc. to Pr02-00)
Prt08-00=3 (neg feedback on AVI2)
Pr04-05=1 (MI3)
So the setpoint can be switched between AVI and Preset1 (value in Pr05-00 and
active via MI3).
Q How to preset speed and master frequency via Modbus
A When Pr02-00=3 (Frequency command by RS-485) and preset speed are active
(Pr04-05 to -08, Pr05-00 to –14, MI3~6 active), the drive doesn’t accept a change of
the master frequency via RS-485 and gives 04 error. It keeps the last frequency
command value before preset speeds were activated.
Only when MI3~MI6 are off (no preset speed selected), you can change the master
frequency by RS-485.
