YASKAWA ELECTRIC SIEP C710616 30B YASKAWA AC Drive T1000A Technical Manual
Setting 1: Continue operation with reduced frequency reference
The drive will continue operation at the frequency reference value set in parameter L4-06. When the external frequency
reference value is restored, the operation is continued with the frequency reference.
n
L4-06: Frequency Reference at Reference Loss
Sets the frequency reference level the drive runs with when L4-05 = 1 and a reference loss was detected. The value is set
as a percentage of the frequency reference when the loss was detected.
n
L4-07: Speed Agreement Detection Selection
Determines when frequency detection is activated.
Setting 0: During run only (no detection while drive output is shut off)
Setting 1: Detection always enabled
n
L4-08: Frequency Agree Condition Selection
Sets whether a frequency agree situation should be determined by the soft-starter output frequency or by the estimated
speed of the motor.
Setting 0: Use the soft starter output frequency to determine frequency agree
Setting 1: Use the motor speed to determine frequency agree
The setting of L4-08 affects the other drive functions listed below.
• Conditions for overtorque/undertorque detection 1 and 2 (L6-01, L6-04) become so that both fault and alarm detection
for overtorque 1 and 2 (oL3, oL4) are possible only during speed agree.
• Frequency agree detection is possible with the following settings for the multi-function output terminals.
• MEMOBUS Monitor Data
