L8-10
Heatsink Cooling Fan
Operation Selection
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.

Heatsink Cooling Fan
Operation Delay
Time
This parameter sets the delay time for the
cooling fan to shut off after the run command
is removed when L8-10 = 0.

OL2 Characteristics
Selection at Low
Speeds
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.
