Notes:
(1) This parameter will appear only if the
optional PCB is installed and dip switch # 2
is set to on. Refer to section
6.5.2 on page
57 for dip switch setting details.
(2)
Tacho Feedback is operational in its
basic form. Additional curves except for the
basic linear curve are optional.
(3) Consult the factory for the correct
tacho selection and mechanical installation.
PULSE TIME

0 –1.0 SEC. Sets RVS-DN’s
PULSE START
TIME.
PULSE START
level is 80% Un.
Intended to start high friction loads that
require high starting torque for a short time.
A pulse of 80% Un without CURRENT
LIMIT is initiated to break the load free.
Pulse duration is adjustable, 0.1–1sec.
After this pulse the voltage is ramped down
to INITIAL VOLTAGE setting before
ramping up again to full voltage according
to the START PARAMETERS settings.
Note:
There is no PULSE START function when
RVS-DN is connected Inside Delta.
