5.3.1 Frequency Reference Source
H1: Command Frequency Selection Method
Range:0: Keypad (Factory Default: 0: Keypad)
1:Terminal
In order for the drive to receive its speed reference from an analog source instead of
the keypad, H1, Command Frequency Source, must be set to 1: Terminal.
5.3.2 User V / F Pattern (See Section 5.2.8 for H2, H3, H4, and H5)
5.3.3 Analog Frequency Control
H6: Analog Input Mode (Factory Default: 0: Voltage)
Range:0: Voltage Input
1: Current Input
2: Voltage + Current Input
H7: Analog Input Filter Gain (Factory Default: 100%)
Range:1 - 200 %
H8: Analog Input Gain (Factory Default: 100%)
Range:50 - 100 %
H9: Analog Input Bias (Factory Default: 5%)
Range:0 - 100 %
H10 Analog Input Direction (Factory Default: 0: Direct)
Range:0: Direct
1: Inverse
In order for the drive to receive its speed reference from an external source instead
of the keypad, H1 must be set to 1: Terminal. H6, Analog Input Mode is used to
select the analog frequency reference method. If a 0 ~ 10 VDC signal is the desired
source of reference, then 0: Voltage should be selected. If a 4 ~ 20 mA. signal is the
source of reference, then 1: Current should be selected. When both of the signals
are used, then 2: Voltage + Current should be selected.
The H7, Analog Input Filter Gain, can be adjusted to set the responsiveness of the
drive output. To obtain a faster response, the gain in H7 is set to a lower value and
vice versa, see Fig. 5.3.1.
