Drive diagnostics via the integrated display
The controllers have an integrated 7−segment display which, depending on the device
version, comprises either 4 or 5 characters.
The display has three different modes:
Automatic display − the parameter saved under status value 1 is displayed when the
ƒ
controller is switched on.
Manual operation display − when the controller is activated during manual
ƒ
operation.
Message display − for errors or warnings. This display has the highest priority and
ƒ
overrides the other two modes.
Operation is carried out via keys T1 and T2.
T1 − operator button to display the status of lower−level devices (in preparation).
ƒ
T2 − operator button used for browsing if several status messages or error messages
ƒ
have occurred at the same time.
In the case of a device replacement, both keys must be operated to transfer the safe
parameters from the memory module to the safety module. Further information on this
topic is provided in the corresponding documentation.
Automatic display
This mode serves to display five preset parameters in a row. Use key T2 to browse the
parameters in ascending order. Using the »Engineer«, the user can define which status
values are shown in the display. The following status values (Lenze setting) are displayed:
Status value 1: Motor output frequency in [Hz]
ƒ
The output frequency is displayed based on the direction of rotation, i.e. CCW rotation
is displayed with a minus sign. The display area ranges from − 999 to 999 Hz and has a
resolution of 1 Hz.
Status value 2: Actual current value in [A], resolution 0.1 A
ƒ
Status value 3: Device utilisation in [%]
ƒ
Status value 4: Motor voltage in [V]
ƒ
Status value 5: DC−bus voltage in [V]
ƒ
Manual operation display (in preparation)
If the operator button is used to switch the controller over to the manual operation
ƒ
mode, "rc" is displayed.
If an error is pending during manual operation, the display changes from "rc" to the
ƒ
error code every 0.5 s. If several errors are pending, they are displayed alternately.
If the operator button is used to switch over between CCW and CW rotation, the
ƒ
motor output frequency is displayed without sign for CW rotation and with a minus
sign for CCW rotation.
