YASKAWA TM.iQp.02 iQpump Drive Programming Manual
Description
When the Drive is installed in an ambient temperature exceeding its
rating, Drive overload (OL2) protection level is reduced.
This parameter assists in protecting the output transistor junctions from
overheating when output current is high and output frequency is low.
0: Disabled
1: Enabled (L8-18 is active)
Enables and disables current limit "A".
0: Disabled
1: Enabled.
Sets the amount of frequency reference reduction when an Overheat
Pre-alarm (OH) is detected.
Hunting Prev
0: Disabled (Hunting prevention function disabled.)
1: Enabled (Hunting prevention function enabled.)
If the motor vibrates while lightly loaded, hunting
prevention may reduce the vibration. There is a loss of responsiveness
if hunting prevention is enabled.
Gain setting for the Hunting Prevention Function.
If the motor vibrates while lightly loaded and n1-01=1, increase the
gain by 0.1 until vibration ceases. If the motor stalls while n1-01=1
decrease the gain by 0.1 until the stalling ceases.
High Slip
Sets how aggressively the Drive decreases the output frequency as it
stops the motor. If overvoltage (OV) faults occur during HSB, this
parameter may need to be increased.
Note: Function Deactivated
Sets the maximum current to be drawn during a HSB stop. Higher n3-
02 settings will shorten motor stopping times but cause increased
motor current, and therefore increased motor heating.
. Note: Function Deactivated
Sets the amount of time the Drive will dwell at E1-09 (Minimum
Frequency). If this time is set too low, the machine inertia can cause the
motor to rotate slightly after the HSB stop is complete and Drive
output is shut off.
. Note: Function Deactivated
Sets the time required for a HSB Overload Fault to occur when the
Drive output frequency does not change for some reason during a HSB
stop. Normally this does not need to be adjusted.
Note: Function Deactivated
Monitor Select
Selects which monitor will be displayed upon power-up when o1-02 =
4.
Selects which monitor will be displayed upon power-up.
1: Auto: Setpoint
2: Output Freq
3: Output Current
4: User Monitor (set by o1-01)

Selects the "U1" monitors displayed on the 4th and 5th lines of the
digital operator display.
0: 3 Mon Sequential (Displays the next 2 sequential U1 monitors.)
1: 3 Mon Selectable (Displays U1 monitors set by o1-07 and o1-08.)
