Chapter 4: AC Drive Parameters
4–64
Over-Voltage Stall Prevention Level Default: 230V series = 390.0V
Default: 460V series = 780.0V
Range: 230V Series - 330.0V to 450.0V
460V Series - 600.0V to 900.0V
When drive is running, if the DC bus voltage exceeds Over-Voltage Stall level
(P6.17), the AC drive will start over-voltage stall prevention.
Braking Voltage Level Default: 230V series = 380.0V
Default: 460V series = 760.0V
Range: 230V Series - 370.0V to 450.0V
460V Series - 740.0V to 900.0V
This parameter establishes the Dynamic Braking Voltage level threshold based on
the DC Bus voltage. With the drive running and with DC Bus voltage above the
braking level threshold, the braking transistor internal to the drive is gated ON,
connecting the external braking resistor across the DC Bus to dissipate the excess
voltage as heat.
Line Start Lockout Default Setting: 00
Settings:
00 Enable Line Start Lockout
01 Disable Line Start Lockout
When this parameter is enabled, the AC Drive will not start the motor when
powered up with a RUN command already applied. The drive must see the RUN
command change from STOP to RUN before it will start.
When this parameter is disabled, the AC Drive will start the motor when powered
up with a RUN command already applied.
• This parameter is available only with AC drive firmware v1.02 or higher.
Refer to P9.39 to determine the drive’s firmware version.
