9.2.1
Functional description
DynaStop
®
allows for generating a speed-dependent torque when the motor is de-
energized or "controller inhibit" is activated. This prevents the application from
excessive acceleration due to external forces (e.g. sagging on inclining tracks)
MOVIGEAR
®
has the following function when the drive is running: In the event of a
voltage failure, the kinetic energy is used to supply the frequency inverter via regenera-
tion. This allows for controlled deceleration.
DynaStop
®
is activated when the regenerative power is insufficient.

9.3.1
Activating the function
Activate the function by setting parameter 8893.0 "Deactivate DynaStop
®
without en-
able signal" to the value "1 = YES (factory setting, see also chapter "Parameters"). This
allows for deactivating the DynaStop
®
function even when the drive is not enabled and
the unit is in "Controller inhibit" state.
WARNING
The electrodynamic deceleration function DynaStop
®
does not allow for a definite stop
at a position.
Severe or fatal injuries.
• Do not use the electrodynamic deceleration function for hoists.
• DynaStop
®
may only be used for inclining tracks after a risk assessment.
NOTICE
Setting the controller inhibit when the drive is running will activate DynaStop
®
. This
can cause high torque loads, which may damage the drive and the application!
Possible damage to property
• Only activate the controller inhibit when the speed is "0".
INFORMATION
Refer to chapter "Technical Data and Dimension Sheets / DynaStop
®
deceleration
torques" for possible deceleration torques.
INFORMATION
For information on how to deactivate the DynaStop
®
function, refer to the "Startup"
chapter.
