Description
High Slip Braking
Sets how aggressively the Drive decreases the output frequency as
it stops the motor using high slip braking (HSB). If Overvoltage
(OV) faults occur during HSB, this parameter may need to be
increased.
Sets the maximum current to be drawn during an HSB stop. Higher
n3-02 settings will shorten motor stopping times but cause
increased motor current, and therefore increased motor heating.
Sets the amount of time the Drive will dwell at E1-09 (Minimum
Frequency) at the end of deceleration. If this time is set too low, the
machine inertia can cause the motor to rotate slightly after the HSB
stop is complete and the Drive output is shut off.
Sets the time required for an HSB overload fault (OL7) to occur
when the Drive output frequency does not change for some reason
during an HSB stop. Normally this does not need to be adjusted.
Monitor Select
Selects which monitor will be displayed in the operation menu upon
power-up when o1-02 = 4.
Selects which monitor will be displayed upon
power-up.
1: Frequency Reference (U1-01)
2: Output Frequency (U1-02)
3: Output Current (U1-03)
4: User Monitor (set by o1-01)
Sets the units of the Frequency References (d1-01 to
d1-17), the Frequency Reference Monitors (U1-01,
U1-02, U1-05), and the Modbus communication
frequency reference.
0: Hz
1: % (100% = E1-04)
2 to 39: RPM (Enter the number of motor poles).
40 to 39999: User display.
Set the number desired at maximum
output frequency.
4 digit number
Number of digits from the right of the
decimal point
Example 1: o1-03 = 12000, will result in frequency
reference from 0.0 to 200.0 (200.0 = Fmax).
Example 2: o1-03 = 21234, will result in frequency
reference from 0.00 to 12.34 (12.34 = Fmax).
Sets the setting units related to V/F pattern frequency related
parameters (E1-04, -06, -09, -11)
0: Hertz
1: RPM
Sets the contrast of the Digital Operator LCD. A setting of "1" is the
lightest contrast and a setting of "5" is the darkest contrast.
