511 Bus Jogging 1 (BUS JOG 1)
Value:
000.0 - f
RANGE
★ 10.0
512 Bus Jogging 2 (BUS JOG 2)
Value:
000.0 - f
RANGE
★ 10.0
Function:
Choose two fixed jog speeds, in Hz for Bus Jog 1 and Bus
Jog 2. They are similar to the jog frequency of parameter
203. Bus jog 1 and 2 can only be activated via serial bus
communication.
Bus Jog only works when parameter 497 is set for Quick
Stop and voltage is applied to terminal 27.
513 Catch-up/Slow-down Value (CATCHup/SL)
Value:
0 to 100% ★ 0
Function:
The output frequency of the drive can be reduced or in-
creased by the value selected here; the value is set as a
percentage of the output frequency at any given time
514 Bus Bit 4 (BUS BIT 4)
Value:
★ Quick-stop (Q-STOP) [0]
DC braking (DC BRAKE) [1]
Function:
Bit 4 of the control word can be used either for quick-stop,
or for DC braking.
515 Bus Bit 11/12 (BUS BIT 11)
Value:
★ Catch-up/slow-down (CATCH″ SLOW) [0]
Choice of digital reference (DIG SPD TYPE) [1]
Function:
Bits 11/12 of the control word can be used either for the
“catch-up/slow-down” function, or for selecting between the
digital speed references defined by parameters 205 through
208 in the same way that terminals 32 and 33 can be used
to select a digital reference.
516 Bus Reference (BUS REFERE)
Value:
-100.00% - +100.00% ★ 0.00
Function:
Used for changing the drive’s reference. It is entered as a
% of f
MAX
. It is sent as a part of a serial command message
as follows:
Parameter no.: 516 bytes 9-12
Data: Required ref. bytes 13-18
Decimal point: Position byte 19
517 Save Data Values (STORE DATA)
Value:
★ Off (OFF) [0]
On (ON) [1]
Function:
Data values that are changed via serial bus communication
are not saved automatically if the AC power is removed.
Parameter 517 must be used if modified data values are to
be saved.
Description of choice:
If
On
is selected, it takes approximately 10 seconds to save
all data values of the parameters; parameter 517 subse-
quently assumes the value of
Off
. Only the data values of
the active menu setup are saved. Each setup must be
saved separately if changes have been made.
NOTE:
The saving function can only be activated when
the drive has stopped.
