(*)without considering bits 7 to bit 15

Note:

The Warning bit "Bit No. 7" can be set at any time. It displays an device-internal

warning message. The evaluation of the warning available is done by reading out the

warning status with the parameter

The Remote bit "Bit No. 9" is always = 0.

The bit Reference value reached "Bit No. 10" is set when the reference value

specified 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 the parameter

instructions).

The bit Limit value active "Bit No. 11" displays that an internal limit is active. This

can, for example, be the present current limit, the torque limit or the overvoltage

limit. All the functions lead to the reference value being quit or not reached.

The bit Warning 2 "Bit No. 15" reports a warning which leads to a fault switch-off

of the frequency inverter within a short time. This bit is set if there is a warning for

motor temperature, heat sink/inside temperature, Ixt monitoring or mains phase

failure.

In the operation mode control via state machine (Local/Remote 412 = 1) the

frequency inverter is controlled via the control word. 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

contents 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).

Release (transition 4) is only possible if the hardware release is available via contact

inputs S1IND/FUF AND (S2IND/STR OR S3IND/STL). They can be firmly wired or also

firmly connected to On/Off via the configuration of the digital inputs. If contact input

S1IND/FUF is switched off, the inverter outputs can be blocked at any time. The drive

then stops freely. There is a transition to "Ready" (0x23, power parts blocked).

The behavior of transition 5 can be set via the parameter

Here, free stopping, shutdown via ramp (reversible) or DC braking (see Chapter "

Behavior in transition 5") can be used.

A fault occurring leads to a switch-over to the "Fault" state.

A fault can only be acknowledged 15 seconds after the occurrence of the

fault, as a blocking time is active internally.
