Delta VFD015EL43W-1 - Current Limit for Speed Search; Skip Frequency 1 Upper Limit; Skip Frequency 1 Lower Limit; Skip Frequency 2 Upper Limit

Chapter 4 Parameters  VFD-EL-W
4-71
Settings 0.1–5.0 sec. Default: 0.5
 When the AC motor drive detects a momentary power loss, it blocks its output and then waits for a period of
time specified by this parameter before resuming operation. Set this parameter at a value that ensures that
any residual regeneration voltage from the motor on the output has disappeared before the drive is activated
again.
 This parameter also determines the waiting time before resuming operation after an External Base Block and
Number of Auto-restarts after Fault (Pr.08.15).
08.08 Current Limit for Speed Search Unit: 1
Settings 30–200% Default: 150
 Limits the drive output current during a speed search.
 When executing a speed search, the V/F curve is defined by the settings in Parameter Group 01.

08.14
Skip Frequency 3 Lower Limit Unit: 0.01
Settings 0.00–400.00 Hz Default: 0.00
 These parameters cause the AC motor drive not to remain in these frequency ranges with continuous
frequency output. Set these six parameters as follows Pr.08.09  Pr.08.10  Pr.08.11  Pr.08.12  Pr.08.13 
Pr.08.14.

Number of Auto-restarts After Fault Unit: 1
Settings 0–10 Default: 0

Auto-reset Time for Restart after Fault Unit: 0.1
Settings 0.1–6000 sec. Default: 60.0
 After an over-current OC or over-voltage OV fault occurs, the AC motor drive can automatically reset/restart
up to ten times.
 Setting this parameter to 0 disables automatic reset/restart operation after any fault.
When enabled, the AC motor drive restarts with speed search, which starts at the last frequency before the
fault.
