YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)
Description
Controls the heatsink cooling fan operation.
0: Fan On-Run Mode - Fan will operate only
when the drive is running and for L8-11
seconds after RUN is removed.
1: Fan always on - Cooling fan operates
whenever the drive is powered up.
This parameter sets the delay time for the
cooling fan to shut off after the run command
is removed when L8-10 = 0.
Adjust the drive overload (OL2) protection
level when the drive is installed in an
environment that exceeds its ambient
temperature rating.
Assists in protecting the output transistors from
overheating when output current is high and
output frequency is low (6Hz and less).
0: Disabled - L8-16 and L8-17 are disabled.
1: Enabled - L8-16 and L8-17 are enabled.
Enables and disables the software current limit
function. This parameter does not typically
require adjustment. Consult the factory before
disabling.
0: Disabled
1: Enabled
Specifies the frequency reference derate when
L8-03 = 4.
Issues a stop command when the output current
is unbalanced as a result of output phase loss.
0: Disabled
1: Enabled
0: Disabled (standard installation)
1: Side-by-Side installation
2: NEMA Type 1
Provides protection to the IGBTs by reducing
the carrier frequency at low speeds.
0: Disabled
1: Enabled
Configures an alarm when the relative output
current rises above 150%.
0: Alarm disabled.
1: Alarm enabled (alarm is output).
