9) Noticeable transition from "Ve" interrupt during stopping:
"Ve" not matched to the "approach distance", solution by reduction of "Ve" or increase of
distance in parameter "F26".
The gear-down point to the approach speed "Ve" is located too close to the level position. This
causes an excessively steep approach from the interrupt point. Remedy: Move the gear-down
point further back until a crawl speed is reached up to the interrupt point. Now increase the
return rounding so that the transition is made without a noticeable crawl distance.
50MHz: Difference between 0E1C and 0E1E too large (try 0E12 below the value of "Ve" so that
the switchback to "I-gain stop" cannot be made).
10) External 24 V supply voltage is short-circuited as soon as an input is activated or
connected at DSV
The 24 V level was exceeded by more than 25 %.
The DSV protection elements have responded.
Please send the device to our factory for examination.
11) Lift travels at half or double speed
Check values for number of gears and suspension.
There can be a problem with counter overflows when the drive wheel or the suspension have
unusual values (f10 and f22 are then changed to revs/min.).
12) Output A9 not removed in levelling zone.
If parameter F7 (P-gain start) is too large, A9 will sometimes not be removed; if k (P-gain run)
is too large, run will be terminated prematurely. Too large results in the motor humming, see
also Point 6) Motor
13) Phase fault message during emergency evacuation
E1 for ...7SZ. or flag 0E62h for ...3SZ., 9SZ. or 10SZ. basis not activated.
14) Run is not terminated correctly ( system is not uniformly flush)
Control signal coming incorrectly. This can be checked either with the FU-Control under point
"Inspect interface", or also using the "Terminal" function in EmoSoftLift (or mode "F3" in the
DOS ter.exe). The typical "bracket messages" for the drive steps must normally be displayed
here. the run was terminated correctly, the last command chain is normally …
(Ve)(go)(LPOS)(AUS) If (LPOS) is missing, for example, then the system has probably
stopped with the mechanical brake. This may have several causes:
The time "Contactor delayed off" or "T2 motor time" or "Restart delay" are smaller than the time
that the DSV needs to travel the remaining distance "F26" after removal of "Ve" or output of
"INT2". Because of this the time "Contactor delayed off" should be set always higher than E24
“Braking delay” + t “Rotor time constant”.
The remaining distance "F26" does not correspond to that in the controller or to the half of the
length of the flush magnets (pure magnet copying), i.e. the distance to achieve flush
alignment.
The necessary "DSV5444/5445" mode was not selected at the lift controller.
