Examples uses of table output function

[Uses of table output function]
• Inverter frequency setting, servo speed control, etc.
1. Inverter frequency setting
The output frequency can be controlled by inputting analog signals (e.g. voltage from 0 to 10 V and current
from 4 to 20 mA) to inverter frequency setting signals.
The analog signals and output signals have the following proportional relationship.
