Multi-Function Analog Output Gain; Carrier Frequency - Omron SYSDRIVE 3G3HV SERIES User Manual

Preparing for Operation
n049

Multi-function Analog Output Gain

Setting range 0.01 to 2.00
• The parameter n049 is used to adjust the analog output gain.
Set Values
• Set n049 to the result obtained from dividing the voltage of the full analog output by 10 V.
• For example, set n048 to 0 and n049 to 0.30 when connecting multi-function analog output terminals
AM and AC to a frequency meter that operates at 3 V maximum. Refer to the following diagram.
n050

Carrier Frequency

Setting range 1 to 9
Note The default-set value of n050 varies with the Inverter model.
• Set the switching frequency (carrier frequency) of the output transistor of the Inverter with n050.
• The noise generation and current leakage of the Inverter will be low if the carrier frequency is set low, in
which case, the motor will generate a more metallic noise.
Set Values
Set value
1 2.5 kHz
2 5.0 kHz
3 8.0 kHz
4 10.0 kHz
5 12.5 kHz
6 15.0 kHz
7 to 9 Varies in proportion to output frequency up to 2.5 kHz. (Refer to the following graphs)
10 7.0 kHz
Note 1. The carrier frequency setting range varies depending on the Inverter capacity.
200-V class and 400-V class, 22 kW max.:
200-V class, 30 to 75 kW; 400-V class, 30 to 160 kW:
400-V class, 185 to 300 kW:
Note 2. For a 400-V Inverter, if the carrier frequency is set to a value higher than the default setting, the
Inverter's rated output current will decrease as shown in the following table. If the Inverter
overload "OL2" is detected prior to the motor overload "OL1," decrease the carrier frequency
setting.
