Frequency Reference Gain; Frequency Reference Bias; Control Circuit Terminal - Omron SYSDRIVE 3G3HV SERIES User Manual

Preparing for Operation
Note 1. Do not set n002 to any value other than the above.
Note 2. The frequency reference input according to the operation mode selection setting will be used
as frequency reference 1 in multi-step speed operation. If the frequency reference is deter-
mined by control circuit terminals, the frequency reference input using the control circuit ter-
minals' analog input will be enabled and the frequency reference 1 parameter setting (n025)
will be ignored. (If, however, the mode is changed to Local mode using the Digital Operator,
then the value set in n025 will be enabled.)
Note 3. Frequency references 2 to 4 (n026 to n028) and the inching frequency reference (n029) used
in multi-step speed operation will be determined by the parameter settings, regardless of the
operation mode selection setting.
H Frequency Reference Type Selection (n042, n046, and n047) through

Control Circuit Terminal

S Select the FV terminal to input the frequency reference within a voltage range from 0 to 10 VDC or
the FI terminal to input the frequency reference within a current range from 4 to 20 mA with n042.
n042
Analog Frequency Reference Voltage/Current Selection
Setting range 0, 1
Set Values
Set value
0 The FV terminal can be used for the analog frequency reference within a voltage range from 0
to 10 VDC.
1 The FI terminal can be used for the analog frequency reference. Set the input level with n043.
Note 1. The FI terminal is a current input terminal for 4 to 20 mA. The FI terminal can be a voltage input
terminal by changing the FI input level with n043 and cutting jumper wire of the PCB. Do not,
however, change the FI terminal to a voltage input terminal unless the Inverter is used for PID
control.
Note 2. Set n042 according to the type of frequency reference.
S Set the frequency reference gain with n046 and the frequency reference bias with n047.
