Manual Parameter Setup
Calculate parameter L3-25 in the formula below:
L3-25 =
Machine Inertia
Motor Inertia
n
L3-26: Additional DC Bus Capacitors
Sets the capacity of any additionally installed DC bus capacitors. This data is used in calculations for Single Drive KEB Ride-
Thru 2. Adjust this setting only if external capacity is connected to the DC bus and Single Drive KEB 2 is used.
No. Name Setting Range Default
L3-26 Additional DC Bus Capacitors 0 to 65000 μF 0 μF
n
L3-27: Stall Prevention Detection Time
Sets a delay time from when the Stall Prevention level is reached and the actual Stall Prevention function is activated.
No. Name Setting Range Default
L3-27 Stall Prevention Detection Time 0 to 5000 ms 50 ms
u
L4: Speed Detection
These parameters set up the speed agree and speed detection functions that can be assigned to the multi-function output
terminals.
n
L4-01, L4-02: Speed Agreement Detection Level and Detection Width
Parameter L4-01 sets the detection level for the digital output functions “Speed agree 1,” “User-set speed agree 1,” “Frequency
detection 1,” and “Frequency detection 2.”
Parameter L4-02 sets the hysteresis level for these functions.
