YASKAWA ELECTRIC SIEP C710606 18F YASKAWA AC Drive – V1000 Technical Manual
Description
0: Sets the Stall Prevention level throughout the entire
frequency range to the value in parameter L3-06.
1: Automatically lowers the Stall Prevention level in the
constant output range. The lower limit value is 40% of L3-06.
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-
oo = 2, 3, 4, 5) settings "Speed Agree 1", "User Set Speed
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-
oo = 13, 14, 15, 16) settings "Speed Agree 2", "User Set
Speed 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 within 400 ms).
0: Stop - Drive will stop.
1: Run at L4-06 Level - 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 x L4-06.
0: No detection during baseblock.
1: Detection always enabled.
0: Match speed with the soft-starter output
1: Match frequency reference and motor speed
Note: In V/f Control, the drive ignores the value set to L4-08
and refers to the soft-starter output to determine whether a
speed agree situation has been reached.
L5: Fault Reset
Use L5 parameters to configure Automatic Restart after fault.
Sets the counter for the number of times the drive attempts to
restart when one of the following faults occurs: GF, LF, oC,
oH1, ov, PF, rH, rr, oL1, oL2, oL3, oL4, STo, Uv1.
Parameter L5-05 determines the how the restart counter is
incremented.
When the drive operates without fault for 10 minutes, the
counter will be reset.
Sets fault contact (H2-oo = E) activation during automatic
restart attempts.
0: Fault output not active.
1: Fault output active during restart attempt.
Sets the amount of time to wait between performing fault
restarts. Enabled when L5-05 is set to 1.
Selects the method of incrementing the restart counter.
0: Continuously attempt to restart and increment counter after
successful restart (same as Varispeed VS616-F7/G7)
1: Attempt to restart with the interval time set in L5-04. Every
trial increments the counter. (same as Varispeed VS606-V7)
L6: Overtorque Detection
Use L6 parameters to configure overtorque detection.
