Hi everybody,
Long time no see...

I have a problem starting my second 4-axis Meldas 520AM (1998) system since I changed all drives to MDS-C1.
I get S01 PR 0018 Alarm and the contactor shut off power to the power supply unit.
The alarm appears on both my 2-axis servo drives. One blips "F1, 18" and "F2, 18". The other one blips "F3, 18" and "F4, 18".
The Spindle drive only shows "E7" since it got emergency shut down by the contactor.
On the control display I get "Servo Alarm S01 PR 0018 X" Note, it only points out the X-axis here. How come?

Before the swap there was no alarm about any encoder communication problem. I have checked the X-axis encoder cable, changed servo motor/encoder unit to another one. Still the same alarm.

My old drives were MDS-A-SVJ-10 for X, Y, B axis and MDS-A-SVJ-20 for Z axis. Spindle drive was MDS-B-SP-75. Power unit was MDS-A-CR-75.
My new drives are MDS-C1-V2 1010 for X, Y axis and MDS-C1-V2-1020 for B, Z axis. Spindle drive is MDS-C1-SP-75. Power unit is MDS-C1-CV-110 + of course an AC line reactor D-AL-11K.
I use the original servo motors/encoders: HA80NT-E33 for X,Y axis, HA100NT-E33 for Z axis and HA40NT-E33 for B axis.
They are all equipped with incremental motor end encoders OSE253 (25 000p/rev).

I have changed following servo parameters before firing up:
SV025 Mtyp: X,Y=from 0001 to 2201, Z=from 0002 to 2202 B=from 0000 to 2200
SV036 Ptyp: X,Y,Z,B=from 1500 to 0011
SV047 EC1: X,Y,Z,B=from 0 to 100

Since I se "18" flickering on all axis, I tend to think it might be a parameter setting error.
Is there another parameter that can cause the 0018 alrm?

Any guidance would be highly appreciated.
Regards
