Status word definition
The status word is 16 bits wide. The less significant byte, the basic status block, consists
of eight status bits with fixed definition that reflect the most important drive states. The
assignment of the more significant status bits varies for different status words.
Basic status
block
The basic status block of the status word contains the condition information required for
nearly any drive application.
Signal "inverter
ready"
The value
inverter ready = 1
in status bit 1 of the status word indicates that the inverter
is ready to respond to control commands from an external control. The inverter is not
ready, if
• MOVIDRIVE
®
signals a fault
• the factory setting is active (setup)
• no supply voltage is present
Signal "PO data
enabled"
With
PO data enabled = 1
, bit 2 signals that the inverter responds to control values and
setpoints from the communication interfaces. The following figure shows the conditions
that have to be met for the PO data to be enabled:
