Figure 7-3 Settings for the limit switch and local operation (key hand) functions
Details on limit switches …
When the drive reaches a limit switch application event 5 is triggered. You can
parameterize the event to inactive level, message, warning or fault. The limit switch is
reset when the drive leaves the limit switch in the opposite direction. This means, for
example, when the positive limit switch triggers and the speed is negative, a falling edge
of the limit switch must be determined.
If a fault was triggered, you can reset the event and then move in the permissible
direction away from the limit switch.
A limit switch mix-up is caught by also polling the speed when the switch is triggered. If
the inverter determines a negative speed when the positive limit switch is triggered, the
inverter is blocked. The device cannot be re-enabled until you turn it off and on again.
Remember that it is essential to reverse the connections of the limit switches or re-
parameterize and save before you turn on the device again.
CAUTION
• When the speed is polled and a value less than ± C40 is determined, no direction can
be assumed. However, to reset the limit switch anyway, you can delay the limit switch
signal with the switchoff delay until the speed is greater than ± C40.
• The limit switches are evaluated internally as break-contacts. When make-contacts are
connected as limit switches, the binary input in D103 or D104 must be selected
inverted (e.g., 4:BE1-inverted).
Details on local operation (key
hand function)
Press the button to access local operation.
• You can enable and disable the drive with the
I/O
button.
• The motor stops when the
ESC
button is pressed.
• Use the buttons to move at the speed specified in D235 as long as the button is
pressed. The value specified in D28 is the acceleration and deceleration ramp.
• A motor potentiometer is simulated with the buttons. The value specified in D28
is the acceleration and deceleration ramp.
CAUTION
If the device remains in the "switch-on disable" device state because the state is
obtained with a given enable (for bus enable and additional enable) and if a change is
then made to local operation, the inverter is enabled when local operation is exited! This
can cause the drive to move.
