OMRON Sysdrive 3G3HV - Detector Cooling Section

n047:
The frequency for 0-V or 4-mA input can be set in 1% units based on the maximum
frequency set with n012 as 100%.

Note The frequency reference gain and frequency reference bias can be set with the GAIN
indicator and BIAS indicator.
Frequency Reference Selection (n024 to n029) through Digital
Operator
Frequency references can be input through the Digital Operator by setting the unit of the
frequency references with n024 and the values of the frequency references with n025 to
n028. The inching frequency reference must be set with n029 if an inching frequency is
required.

Determine the display method of the maximum frequency set with n012. A frequency less
than the maximum frequency will be displayed proportionally.
Example: Set n024 to 1100 so that “10.0” will be displayed at the maximum frequency.
10.0 →1100

Set frequency references 1 to 4 with n025 to n028. The multi-step speed command must
be selected to use frequency references 2 to 4. Refer below, Multi-function Input Selection
