Set Values
Value Description
0 The settings of the FREQUENCY adjuster in the Digital Operator are enabled. (See note 1.)
1 Frequency reference 1 (n024) is enabled.
2 The frequency reference control terminal (for 0- to 10-V input) is enabled. (See note 2.)
3 The frequency reference control terminal (for 4- to 20-mA current input) is enabled. (See note
3.)
4 The frequency reference control terminal (for 0- to 20-mA current input) is enabled. (See note
3.)
5 The pulse train command control input is enabled.
6 Frequency reference (0002 Hex) through RS-422/485 communications is enabled.
7 Multi-function analog voltage input (0 to 10 V) is enabled. This setting is not required unless
two analog inputs are required in PID control.
8 Multi-function analog current input (4 to 20 mA) is enabled. This setting is not required unless
two analog inputs are required in PID control.
9 Frequency reference input from option (DeviceNet Communications Unit) is enabled.
Note 1. The maximum frequency (FMAX) is set when the FREQ adjuster is set to MAX.
Note 2. The maximum frequency (FMAX) is set with 10 V input.
Note 3. The maximum frequency (FMAX) is set with 20 mA input, provided that SW2 on the control
PCB is switched from V to I.
