EM500 Open-Loop Vector Control Inverter User Manual

The VF separation is generally used for occasions such as induction heating,
inversion power supply and torque motor control.
In VF separation control, output frequency can be set by F05.08 as well as analog
input, high speed pulse, PID or communication setting. In nonnumeric setting, 100% of
each setting refers to motor’s rated voltage. When the set percentage of analog output is
negative, then take the set absolute value as effective value.
F05.07=0: Numeric Setting of VF Separation Voltage (F05.08)
VF separation output voltage is determined by the numeric setting of VF separation
voltage (F05.08).
F05.07=1: AI1
F05.07=2: AI2
F05.07=3: AI3
F05.07=4: High-Frequency Pulse Input (X7)
VF separation output voltage is determined by AI/HDI (percentage) * Numeric
Setting of VF Separation Voltage (F05.08).
Please refer to the description of F00.04 for detailed explanations of AI1-AI3 and
X7. F00.04 has the same meanings as AI1-AI3 and X7. 100.00% is the percentage
inputted through F05.08 (Numeric Setting of VF Separation Voltage).
F05.07=5: Process PID
VF separation output voltage is determined by the process PID (see 7.10).
F05.07=6: Communication Percentage Setting
The VF separation output voltage is determined through communication.
If inverter is under master-slave communication control (F10.05=1) and present
inverter is a slave (F10.06=0), the VF separation output voltage is set as “700FH
(Communication Percentage Setting) * F01.02 (Motor Rated Voltage) * F10.08
(Receiving Proportionality Factor of Slave)”. The range of 700FH is 0.00% to
100.00%. See Table 12-2 for details.
