In this menu, you can configure the
inputs and outputs of the unit.
Here you can revise
the rotational sense assignment of the encoder signals. The same effect can be
achieved by exchanging wires A and B or -A and -B at the converter terminals.
Note: In case synchronous machines are used this
parameter is determined automatically and must not be changed for this reason!
Filtration of the
encoder signal can be set here. This enables faulty sensor signals to be
smoothened.
Note: A high
filtration degree (e.g. T filter = 4) can lead to a worsening of control
behaviour and cause vibrations on systems susceptible to vibration
Here, you can configure the function of the digital
inputs:
Acknow. errors: Function "External fault
acknowledgement input". A fault can be acknowledged by an external +24V
signal on this input.
Contactor monitoring: Function "Monitoring drive
contactors". The drive contactors are checked for a drop at a standstill
(500 msec after opening the ZS relay) via auxiliary contacts, i.e. the signal
at the digital input must be 0 V.
Brake Start: Function „Monitoring of opening of brake upon
start“. Via a +24 V signal the VVVF controller is informed that the brake is
open.
Here, you can choose
between parallel and binary drive commands encoding:
·
Parallel control
(standard)
·
Binary encoding
For binary encoding
of the drive commands, VVVF controller inputs V1, V2, V3, V4 are used. The
assignment is as follows:
Driving stage VVVF controller |
Cl. 16 (V1) |
Cl. 17 (V2) |
Cl. 18 (V3) |
Cl.19 (V4) |

Here, you can
configure the VVVF controller for operation with only one direction signal. To
do this, the parameter must be set to 1.
Here the Outputs of the VVVF can be configured.
By setting a 1 the inverter signals the magnetized motor by the relay ZS.
For more details, please refer to
the VVVF controller manual.
