Pulse Input Command (Speed Command Selection) - Toshiba TOSVERT VF-AS3 Instruction Manual

3. 2 Pulse input command
(speed command selection)
It is possible to input inverter operation frequency command by PG pulse signals.
This command cannot be used when vector control operation with sensor is effective.
• Inverter output frequency can be controlled in ratio with the pulse output signal from the pulse oscillator.
• By inputting two-phase pulse with 90 degrees phase difference, it is possible to input forward and
reverse rotation commands.
See 2.2.3 for detail connection

* Calculation of the reference frequency
The input pulse frequency is calculated to the percent base data. The calculated percent data is
converted to the frequency in accordance with 2 point setting (from [F234] to [F237]). Refer to the
below figure. By inputting two-phase pulse with 90 degrees phase difference, it is possible to input
forward and reverse rotation commands.
