Other parameters
Startup
6.2.4 P553 DCS serial number
Display value that cannot be changed.
Parameter P553 shows the serial number of option DCS..B. The displayed serial
number must be identical with the serial number on the nameplate of the DCS..B option,
which is attached to MOVIDRIVE
®
MDX61B. You have to enter the serial number in the
configuration report (see chapter "Validation").
6.2.5 P554 CRC DCS
Display value that cannot be changed.
The parameter CRC DCS shows the CRC (cyclic redundancy check) of the program
stored on the DCS..B option. You have to enter the CRC in the configuration report (see
chapter "Validation").
6.2.6 P555 Error response DCS / P556 Alarm response DCS
Factory setting: IMM. STOP
/ FAULT
If option DCS..B signals an error (P555) or an alarm (P556), the inverter performs the
set response (No response / Display error). As the safety-oriented switching off is
performed by the DCS..B option or a higher-level safety controller, SEW-EURODRIVE
recommends to set P555 and P556 to "Display error".
6.2.7 P557 DCS actual position source
Setting range: Motor encoder (X15)
/ Ext. Encoder (X14) / Absolute encoder (X62)
If the option "Backplane bus inc." or "Backplane bus abs." is set in the MOVISAFE
®
Assist/Config software interface, the setting in P557 determines which encoder signal is
evaluated by the DCS..B option.
6.3 Other parameters
6.3.1 P350/351 Direction of rotation reversal 1/2
Setting range: ON / OFF
• ON: Above definition is reversed. The assignment of limit switches is maintained.
When the motor turns in CLOCKWISE direction, the drive will be properly stopped
once it hits the right limit switch. When using this parameter, it is important to carefully
check that the limit switch is connected properly and the reference point and travel
positions are defined correctly.
•OFF
: The SEW definition applies.
Direction of rotation
reversal
Positive setpoint
(positive direction of travel)
Negative setpoint
(negative direction of travel)
OFF Motor turns clockwise Motor turns counterclockwise
ON Motor turns counterclockwise Motor turns clockwise
INFORMATION
Altering the "Direction of rotation reversal" parameter after the system has been refer-
enced causes the system to lose its reference point for the absolute position. The
result may be undesirable movements of the axis.
