Control Via State Machine - BONFIGLIOLI Vectron ACTIVE CUBE Manual

The status word reflects the operation state.
Ready
Operation enabled
Fault
(*)without considering bits 7 to bit 15
Note:
The Warning bit "Bit No. 7" can be set at any time. It indicates a device-internal
warning message. The evaluation of the present warning is carried out by reading out
the warning status with parameter
The Remote bit "Bit No. 9" is always = 0.
The bit Reference value reached "Bit No. 10" is set whenever the specified refer-
ence value has been reached. In the special case of power failure regulation, the bit is
also set if the power failure regulation has reached the frequency 0 Hz (see operating
instructions). For "Reference value reached" there is a hysteresis (tolerance range),
which can be set via parameter
tions).
The bit Limit value active "Bit No. 11" indicates that an internal limit is active. This
can, for example, be the present current limit, the torque limit or the over-voltage
limit. All the functions lead to the reference value being quit or not reached.
The bit Warning 2 "Bit No. 15" indicates a warning which leads to a fault switch-off
of the frequency inverter within a short period of time. This bit is set if there is a
warning for motor temperature, heat sink/inside temperature, Ixt monitoring or mains
phase failure.
13.4.3
In the operation mode control via state machine (
quency inverter is controlled via the control word in PZD1. The possible states are
shown in the diagram. The values on the transition identify these transitions between
the states. The codes shown on the transitions, 0xnn, are the control word needed in
each case (Bit 0 to Bit 7). The codes contained in the states, 0xnn, display the con-
tents of the state word (Bit 0 to Bit 7).
After mains on (Reset), the frequency inverter is in the state "Switch-on inhibit"
(0x40). With the transitions 4 and 5, there is a change between "Operation enabled"
(0x27, power parts enabled, drive working) and "Ready" (0x23, power parts blocked).

The occurrence of a fault leads to a switch-over to the "Fault" state.
A fault can only be acknowledged 15 seconds after its occurrence, as a
blocking time is active internally.
