Manual Parameter Setup
Parameter L3-25 can be calculated by:
■
L3-26: Additional DC Bus Capacitors
Sets the capacity of any additional DC bus capacitors that have been installed. This data is used in calculations for Single
Drive KEB Ride-Thru 2. This setting needs to be adjusted only if external capacity is connected to the drives DC bus and
Single Drive KEB 2 is used.
■
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.
◆ L4: Speed Detection
These parameters set up the speed agree and speed detection functions which can be assigned to the multi-function
output terminals.
■ 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.
Refer to H2-01 to H2-03: Terminal M1-M2, M3-M4, and M5-M6 Function Selection on page 190, Settings 2, 3, 4, and
5.
■
L4-03, L4-04: Speed Agreement Detection Level and Detection Width (+/-)
Parameter L4-03 sets the detection level for the digital output functions “Speed agree 2,” “User-set speed agree 2,”
“Frequency detection 3,” and “Frequency detection 4.”
Parameter L4-04 sets the hysteresis level for these functions.
Refer to H2-01 to H2-03: Terminal M1-M2, M3-M4, and M5-M6 Function Selection on page 190, Settings 13, 14, 15,
and 16.
