L4: Speed Detection
Use L4 parameters to configure frequency detection operation.
L4-01
<15>
Speed Agreement Detection
Level
These parameters configure the multi-function output (H2-
 = 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.

Speed Agreement Detection
Level (+/-)
These parameters configure the Multi-Function Output
(H2- = 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.

L4-05
Frequency Reference Loss
Detection Selection
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.
0,1 0 A A A 49D 195
L4-06
Frequency Reference at
Reference 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.
0.0 to
100.0
80.0% A A A 4C2 196
L4-07
Speed Agreement Detection
Selection
0: No detection during baseblock.
1: Enable frequency detection during baseblock (BB).
0 to 1 0 A A A 470 196
L5: Fault Restart
Use L5 parameters to configure Automatic Restart after fault.
L5-01
Number of Auto Restart
Attempts
Sets the counter for the number of times the drive attempts
to restart when one of the following faults occurs: GF, LF,
oC, ov, PF, rH, rr, oL1, oL2, oL3, oL4, 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.
0 to 10 0 A A A 49E 196
L5-02
Auto Restart Fault Output
Operation Selection
Sets fault contact (H2- = E) activation during
automatic restart attempts.
0: Fault output not active.
1: Fault output active during restart attempt.
0,1 0 A A A 49F 197
L5-04 Fault Reset Interval Time
Sets the amount of time to wait between performing fault
restarts. Enabled when L5-05 is set to 1.

L5-05
Fault Reset Operation
Selection
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)
