■ Timer Function Operation
The timer function switches on when the timer function input closes for longer than the value set to b4-01. The timer
function switches off when the timer function input is open for longer than the value set to b4-02.
Figure 5.2 illustrates
the timer function operation:

◆ b6: Dwell Function
The Dwell function temporarily holds the frequency reference at a predefined value for a set time then continues
accelerating or decelerating.
Figure 5.3 shows how the Dwell function works.
Note: Set the stopping method to "Ramp to Stop" (b1-03 = 0) to use the Dwell function.

■ b6-01, b6-02: Dwell Speed, Dwell Time at Start
Parameter b6-01 determines the speed that is held or the time set in b6-02 during acceleration.
■ b6-03, b6-04: Dwell Speed, Dwell Time at Stop
Parameter b6-03 determines the speed that is held for the time set in b6-04 during deceleration.
◆ b7: Droop Control (CLV/PM)
Droop control automatically balances the load level between two motors driving the same load. The drive in which Droop
control is activated shifts the load from one motor to another by automatically reducing the speed when the torque
reference rises, and automatically increasing the speed when the torque reference falls.
Note: Disable Inertia Compensation (n5-01 = 0) whenever using Droop control.
