Sets the time needed to accelerate the
uncoupled motor at rated torque from stop to
the maximum frequency.
Setting the drive capacity to parameter o2-04
or changing E2-11 will automatically set this
parameter for a 4-pole motor.
Sets the ratio between the motor and machine
inertia.
L4: Frequency Detection
Use L4 parameters to configure frequency detection operation.
These parameters configure the multi-function
output (H2-
Fout Agree 1", "Fref/Set Agree 1", "Frequency
Detection 1," and "Frequency detection 2".
Parameter L4-01 sets the level while parameter
L4-02 sets the hysteresis for the Speed
Detection Output Function.
These parameters configure the Multi-Function
Output (H2-
"Fref/Fout Agree 2", "Fref/Set Agree 2",
"Frequency Detection 3," or "Frequency
Detection 4".
Parameter L4-03 sets the level while parameter
L4-04 sets the hysteresis for the Speed
Detection Output Function.
Sets operation when the frequency reference is
lost (reference drops 90% or more of within
400 ms).
0: Stop - Drive will stop.
1: Run at L4-06 PrevRef - Drive will run at the
percentage set in L4-06 of the frequency
reference before loss.
Sets the frequency reference when a reference
loss was detected and L4-05 = 1. Reference
will be: Fref = Fref at time of loss L4-06.
0: No detection during baseblock.
1: Detection always enabled.
