b3-19: Number of Speed Search Restarts
Sets the number of times the drive should attempt to find the speed and restart the motor using Speed Estimation Speed Search.
This function has no influence when Current Detection Speed Search is used (b3-24 = 0).

b4: Delay Timers
The timer function is independent of the drive operation and can be used to delay the switching of a digital output triggered
by a digital input signal. An On-delay and Off-delay can be separately set. The delay timer can help to get rid of chattering
switch noise from sensors.
To enable the timer function, a multi-function input must be set to “Timer input” (H1-
oo
= 18) and a multi-function output
must be set to “Timer output” (H2-
oo
= 12). Only one timer can be used.

Timer Function Operation
When the timer function input closes for longer than the value set in b4-01, the timer output switches on. When the timer
function input is open for longer than the value set in b4-02, the timer output function switches off. The following diagram
demonstrates the timer function operation.

b5: PID Control
The drive has a built in PID (Propor In Derivative) controller that can be used for closed loop control of system
variables such as pressure, temperature etc. The difference between the target and the feedback value (deviation) is fed into
the PID controller. The PID controller adjusts the drive output frequency in order to minimize the deviation, providing an
accurate control of the system variables.
