Yaskawa GPD503 Drive - Manual (Page 87)

2.33 V/f PATTERN - CUSTOM
A. Cn-01: Output Voltage Regulator Factory Setting: 230 / 460 / 575 V
Range: 0.0 to 255.0 (230V)
0.0 to 510.0 (460V)
0.0 to 733.1 (575V)
This constant sets the output voltage to be regulated. If Sn-02 is set to a value in the
range
00 to 0E , then changing Cn-01 will automatically effect the voltage constants
(Cn-03, Cn-06 and Cn-08; see section B of this feature description) proportionally. If
Sn-02 is
0F , then Cn-01 has no effect on the voltage constants, and the output voltage
would be determined by the voltages programmed into Cn-03, Cn-06 and Cn-08.
NOTE: Before changing Cn-01, refer to the examples below.

* For this condition, Custom V/Hz Pattern should be used (Sn-02 = 0F ), and Cn-01 set to Input Voltage.
For 460V units only:
• If Cn-01
*
400, then overvoltage trip point = 800 Vdc
• If Cn-01

400, then overvoltage trip point = 700 Vdc.

500, then overvoltage trip point = 1040 Vdc
• If Cn-01

500, then overvoltage trip point = 910 Vdc.
