DCS 500B / DCP 500B Operating Instructions
Actual current changed faster than allowed
The rate of current change is monitored.
Check: - Setting of current reference slope
[P406] and CURRENT_RISE_MAX
[P418];
Level and setting of line voltage
and motor voltage; setting of
current controler
Speed feedback (measurement) fault
Check: - Incremental encoder and connec-
tion cable, encoder power supply
(feedback might be too low);
- Tacho polarity and voltage
(does a total mismatch exist?)
- Electronic boards SDCS-CON-x,
SDCS-IOB-3, SDCS-POW 1;
- Connection converter – armature
circuit open?
- Correct setting for selection of
speed feedback monitoring?
(Converter) Type coding fault
SDCS-PIN-xx board not connected to board
SDCS-CON-x or SDCS-PIN-xx not coded.
Check: - Flat cables X12 and X13 O.K.?
- Faulty coding on SDCS-PIN-xx?
- Correct coding of unit size C4?
Note
: This fault signal will be shown, if jumper S2 (on board
SDCS-CON-x) is in position 1–2 while switching ON the elec-
tronics supply. In that case select BACKUP-STOREMODE
[11202], save the paramter set, switch OFF the electronics,
reset jumper S2 and switch ON the electronics again.
Backup read fault (Parameter saving fault)
Cause: Wrong or missing checksum, data error
while writing or reading.
Note : T ry again BACKUP-STORE-MODE; for that purpose
- Move jumper S2 (on board SDCS-CON-x) to Pos. 1–2
with electronics supply switched OFF;
- Switch ON electronics again;
- Select BACKUPSTOREMODE [11202];
- Save default parameter set;
- Switch OFF electronics;
- Reset jumper S2 to ist original position;
- Switch ON electronics again.
If display shows F 18 once again, change SDCS-CON-x
board!
