7.2.4 Status Register
The MDD 100 has a status register, read by I-STATUS. It is a 32-Bit variable that contains
all error and status information. The internal behavior of the drive to the different bits can be
set by G-MASKE1, G-MASKE2, G-MASKW and G-MASKD. According to the setting of the
different masks, the drive detects an error, warning or does not react at all. The different
bits have default values and also limitations on attribution to the masks.
─ No 3-phase supply from the
mains
─ check fuses in the mains
─ check electrical supply
─ Drive system is enabled
without mains applied
─ check fuses in the mains
─ check electrical supply
─ Drive is enabled, before
DC – link charged and vice versa
─ internal regen resistor
damaged
─ mains supply voltage too low
when drive is enabled
─ disable drive before the DC-link
voltage crosses the under voltage
threshold set by G-VBUSM
─ No holding brake connected
with M-BRAKE = 1
─ Short circuit at the holding
brake output
─ Connect motor with holding brake
─ Check wiring of the holding brake
─ Set M-BRAKE = 0 if no brake is at
the motor
─ Check wiring of the holding brake
─ Check holding brake
─ No holding brake connected
with M-BRAKE = 1
─ Internal brake supply switch is
defect
─ Connect motor with holding brake
─ Set M-BRAKE = 0 if no brake is at
the motor
─ replace drive
─ motor thermostat has
switched off
─ break in feedback cable or
connectors
─ check why the motor became
so hot (undersized, bad
environmental conditions)
─ check feedback cable and
connectors, replace it, if
necessary
