1. The Inverter in speed search operation will work according to the speed search V/f
characteristics set with n054 and when the output current becomes less than the
speed search operation level set with n052, the Inverter will have normal acceleration
output.
2. The speed search command must be ON for at least the minimum baseblock time set
with n053 after the run command is input, otherwise the speed search operation is not
available.
3. Adjust the minimum baseblock time set with n053 for the most suitable timing to start
the speed search operation.
4. It is usually not necessary to change the default-set values of n052 and n054. Set
n052 to a smaller value if the motor does not restart after the speed search operation
completes.
5. Input the run command in 5 ms or more after the speed search command is input to
permit the Inverter to be in reliable speed search operation.
Integral Value of PID Control Reset Command/PID Control Invalidating
Command (Set Value = 18 or 19)
• Integral Value Reset (Set Value = 18)
If the integral value reset command is input, the integral value used for
PID control will be reset and the integral operation output will be zero.
The integral operation output will remain zero while this command is
input.
Input this command to stop the integral operation to temporarily prevent
rapid changes of the output of the Inverter.
• PID Control Invalidating Command (Set Value = 19)
Use this command to change the type of control performed by the Inverter
from PID control, such as JOG control, to the usual control,
such as constant speed control with a frequency reference, and vice
versa.
The Inverter will stop performing PID control if this command is input
and the Inverter will use input to the FV terminal as a frequency reference.
If n002 is set to 0 or 1, however, the Inverter will use frequency
references 1 to 4.
Timer Function Input (Set Value = 20)
Timer function input is a standard sequential input. By setting appropriate
delay time values with n077 and n078, the Inverter can prevent the
sensor from chattering.
The Inverter will turn ON timer function output if timer function input to
the Inverter is ON for a period longer than the timer function ON-delay
time set with n077.
The Inverter will turn OFF timer function output if timer function input to
the Inverter is OFF for a period longer than the timer function OFF-delay
time set with n078.
