YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)
Description
Sets the DC Bus undervoltage trip level. If this
is set lower than the default setting, additional
AC input impedance or DC bus reactance may
be necessary. Consult with the manufacturer
before changing this parameter setting.
Sets the time required to decelerate to zero
speed when a KEB command is input from a
multi-function input terminal.
Set the time (in seconds) to accelerate to the set
speed after recovery from a momentary power
loss. If setting = 0.0, then active acceleration
time is used instead.
Sets the percentage of output frequency
reduction at the beginning of deceleration
when a KEB command is input from multi-
function input.
Reduction = (slip frequency before KEB) x
L2-08 x 2
Sets the desired value of the DC bus voltage
during KEB.
0: The DC bus voltage during KEB becomes
E1-01 x 1.22. Desired DC bus voltages for OV
suppression and Stall Prevention during Decel
become E1-01 x 1.56.
1: Enables L3-16 and L3-17.
L3: Stall Prevention Function
Use L3 parameters to configure the stall prevention function.
Selects the stall prevention method used to
prevent excessive current during acceleration.
0: Disabled - Motor accelerates at active
acceleration rate. The motor may stall if load is
too heavy or accel time is too short.
1: General Purpose - When output current
exceeds L3-02 level, acceleration stops.
Acceleration will continue when the output
current level falls below the L3-02 level.
2: Intelligent - The active acceleration rate is
ignored. Acceleration is completed in the
shortest amount of time without exceeding the
current value set in L3-02.
