412 = "2 - Control via remote contacts" the frequency inverter is controlled via the control word in PZD1, with the bits 0 to 5 corresponding to the contact inputs S1IND to S6IND. In addition, two virtual contact inputs S7IND and S8IND are available. These virtual contact inputs are not supported as a standard feature and are reserved for special applications. In the use of the remote contact, the frequency inverter behaves in the same way as in control via the hardware contact inputs. The meaning of these inputs can be seen from the operating instructions.
Note:
Release is only possible if the hardware release is available via digital input S1IND.
State machine:
The values in the states report the feedback message via the state word (Bit 0 to 6) in

Note:
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.
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 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 structions).

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.
