External 24 V supply of RMIO board

In crane applications, external voltage is typically connected to the RMIO board to
keep the software running even if the main power supply is disabled. If the external
auxiliary voltage is used, parameter
EXTERNAL 24V. The default value of the parameter is INTERNAL 24V.

Slowdown

This function limits speed to a preset level (parameter SLOW DOWN REF 11.12) if
the 10.09
of movement and allows full speed in the opposite direction as long as the supply
voltage (AMC board supply) is not switched off. If the voltage has been switched off
and the input SLOWDOWN is active (DI = 0), then only slow speed is allowed in both
directions.
By setting parameter
are available for wiring slowdown limit switches to the drive. Slowdown forward (UP)
is wired to digital input 3, Slowdown reverse (down) to digital input 4. If input 3 is
active (DI = 0), speed is limited to the slowdown reference level in the forward (up)
speed direction, but not limited in the reverse direction (down). And vice versa if
input 4 is active (DI = 0). If both inputs 3 and 4 are not active (DI = 1), there is no
slowdown speed limitation in any direction, and full speed is allowed. See
Slowdown and End limit
If the drives are in a Master/Follower configuration and in EXT2 control, then all the
drives will run within the slowdown limit if Slowdown is activated in any of the drives.
The drive displays SLOW DOWN UP and SLOW DOWN DOWN warning messages
according to the Slowdown condition active.
