5.9 n: Special Adjustments
212 YASKAWA ELECTRIC SIEP C710606 44B YASKAWA AC Drive T1000V Technical Manual
■ n8-91: Output Voltage Limit ld Limit
Sets the limit value for the ld operation of the feedback type output voltage limitation. This setting is available only at n8-
87 = 0.
Note: This parameter is valid from software version 6002 or later.
◆ n9: Hardware Settings
Using these parameters, the drive output voltage can be adjusted.
■
n9-10: AVR Time Constant
Sets the delay time constant that is used to adjust the output voltage when the DC bus voltage changes.
■
n9-12: On-Delay Compensation Time
Sets the time value used for IGBT On-delay compensation.
■
n9-62: On-Delay Compensation Derating Start Frequency
Sets the frequency at which the drive begins to compensate the output voltage for the IGBT On-Delay.
■
n9-63: On-Delay Compensation Disable Frequency
When operating a high-speed motor at low speeds, n9-62 sets the frequency at which the drive stops compensating the
switching delay in the DC bus.
