YASKAWA TOEPYAIHV6002A HV600 Drive Programming
Description
V/f OLV/PM OLV/PM EZOLV
Sets the method of Stall Prevention During Acceleration.
0 : Disabled
1 : Enabled
2 : Intelligent (Ignore Decel Ramp)
V/f OLV/PM EZOLV OLV/PM
Sets the output current level to activate the Stall Prevention function during acceleration as
a percentage of the drive rated output current.
V/f OLV/PM OLV/PM EZOLV
Sets the lower limit for the stall prevention level used in the constant output range as a
percentage of the drive rated output current.
V/f OLV/PM EZOLV OLV/PM
Sets the method that the drive will use to prevent overvoltage faults when decelerating.
Note:
The setting range changes when the A1-02 [Control Method Selection] value changes:
• When A1-02 = 5 [OLV/PM], the setting range is 0 to 2.
• When A1-02 = 8 [EZOLV], the setting range is 0, 1.
0 : Disabled
1 : General Purpose
2 : Intelligent (Ignore Decel Ramp)
4 : Overexcitation/High Flux
V/f OLV/PM EZOLV OLV/PM
Sets the function to enable and disable Stall Prevention During Run.
Note:
• An output frequency lower than 6 Hz will disable Stall Prevention during Run. The
L3-05 and L3-06 [Stall Prevent Level during Run] settings do not have an effect.
• The default setting changes when the A1-02 [Control Method] value changes:
–A1-02 = 0, 5 [V/f, OLV/PM]: 2
–A1-02 = 8 [EZOLV]: 3
0 : Disabled
1 : Deceleration Time 1 (C1-02)
2 : Deceleration Time 2 (C1-04)
3 : Intelligent (Ignore Decel Ramp)
V/f OLV/PM OLV/PM EZOLV
Sets the output current level to enable the Stall Prevention function during operation as a
percentage of the drive rated output current.
Note:
This parameter is applicable when L3-05 = 1, 2 [Stall Prevention during RUN =
Deceleration Time 1 (C1-02), Deceleration Time 2 (C1-04)].
V/f OLV/PM EZOLV OLV/PM
Sets the overvoltage suppression function.
0 : Disabled
1 : Enabled
V/f OLV/PM EZOLV OLV/PM
Sets the target value for the DC bus voltage when the overvoltage suppression function and
the Decel Stall Prevention function (Intelligent Stall Prevention) are active.
V/f OLV/PM EZOLV OLV/PM
Sets the proportional gain used to control the DC bus voltage.
V/f OLV/PM EZOLV OLV/PM
Sets the proportional gain to calculate acceleration and deceleration rates.
V/f OLV/PM EZOLV OLV/PM
Sets the momentary deceleration time that the drive will use when it tries to accelerate a
PM motor and detected motor stalls. This function is applicable when L3-01 = 1 [Stall
Prevent Select duringAccel = General Purpose].
