Yaskawa CIMR-UU4A0034A [173/644] B3 25 speed search wait time

Yaskawa CIMR-UU2A0081F [173/644] B3 25 speed search wait time
n
b3-25: Speed Search Wait Time
Sets
the wait
time between Speed Search restarts. Increase the wait time if problems occur with overcurrent or if an SEr fault
occurs.
No. Name Setting Range Default
b3-25 Speed Search Wait Time 0.0 to 30.0 s 0.5 s
n
b3-27: Start Speed Search Select
Selects
a condition
to activate Speed Search Selection at Start (b3-01). Set this parameter to 1 when using a sequence in which
operation starts when the frequency reference exceeds the minimum output frequency while the Run command is active.
No. Name Setting Range Default
b3-27 Start Speed Search Select 0, 1 0
Setting 0: Triggered when a Run Command Is Issued (Normal)
Setting 1: Triggered when an External Baseblock Is Released
n
b3-29: Speed Search Induced Voltage Level
Lower
this value in small increments if changes are necessary. Setting this value too low will prevent the drive from performing
Speed Search. There is normally no need to change this parameter from the default value.
No. Name Setting Range Default
b3-29 Speed Search Induced Voltage Level 0 to 10% 10%
n
b3-31: Speed Search Operation Current Level 1 (Current Detection Type 2)
Sets
the current
level used to limit the output current during Current Detection Type Speed Search 2 as a ratio to E2-03, Motor
No-Load Current.
The current level is determined for a no-load current that is 30% of the rated motor current when the setting value of E2-03
is less than or equal to 30% of the rated motor current.
Note: If the setting value is too large, a stopped inductive motor may accelerate too quickly. In such cases, set this parameter to a value that is
smaller than the rated motor current.
No. Name Setting Range Default
b3-31
Speed Search Operation Current Level 1 (Current Detection Type
2)
1.50 to 3.50 1.50
n
b3-32: Speed Search Operation Current Level 2 (Current Detection 2)
Sets
the current
level at which to end the Speed Search for Current Detection Type Speed Search 2 as a ratio to E2-03, Motor
No-Load Current.
The current level is determined for a no-load current that is 30% of the rated motor current when the setting value of E2-03
is less than or equal to 30% of the rated motor current.
No. Name Setting Range Default
b3-32 Speed Search Operation Current Level 2 (Current Detection 2) 0.00 to 1.49 1.20
n
b3-33: Speed Search Selection when Run Command Is Given during Uv
Activates
and deactivates
Speed Search at start in accordance with whether a Run command was issued during an undervoltage
(Uv) condition. Function is active when a momentary power loss (L2-01 = 1 or 2), Speed Search at start (b3-01 = 1), and
coasting to a stop (b1-03 = 1) are enabled.
Note: 1. Use a sequence that will hold the Run command even during momentary power losses when the Momentary Power Loss Operation
Selection is enabled (L2-01 = 1 or 2).
2. Disable this parameter for a machine in which the motor will stop during a momentary power loss.
No. Name Setting Range Default
b3-33 Speed Search Selection when Run Command is Given during Uv 0, 1 0
