If you want to deactivate quick stop:
• Apply a voltage between 13 and 30V across terminals 21 or 22
(CCW rotation).
• If you have set C042 to -1- via the keypad or one of the
LECOM interfaces, deactivate quick stop in addition by setting
C042 to -0-.
Select direction of rotation
When operating with terminal control, not only the quick stop is
deactivated by applying a HIGH signal across terminal 21 or 22,
but also the direction of rotation is selected. Depending on the
terminal, CW or CCW rotation results from a positive main set-
value (set-value 1/JOG frequency).

If you have selected a configuration with additional set-value (see
page 48), please note that a change of the direction of rotation only
inverts the main set-value, not set-value 2.
Changing the functions of terminals 21, 22
Code C176 can be used to arrange the functions of terminals 21
and 22 such that quick stop and CW/CCW rotation are independent
of each other.
