EM Brk On Delay
Sets the time the drive will remain at
minimum frequency before stopping
and de-energizing the brake coil relay
when Parameter 137 (Stop Mode) is
set to Option 8 or 9.
Parameter Number 261

MOP Reset Sel
Sets the drive to save the current MOP
Reference command.
0 = Zero MOP Ref
This option clamps Parameter 169
(Internal Freq) at 0.0 Hz when drive is
not running.
1 = Save MOP Ref (Default)
Reference is saved in Parameter 169
(Internal Freq).

DB Threshold
Sets the DC bus Voltage Threshold for
Dynamic Brake operation. If the DC
bus voltage falls below the value set
in this parameter, the Dynamic Brake
will not turn on. Lower values will
make the Dynamic Braking function
more responsive, but may result in
nuisance Dynamic Brake activation.

ATTENTION: Equipment damage may result if this parameter is set to a value that
causes the dynamic braking resistor to dissipate excessive power. Parameter settings
less than 100% should be carefully evaluated to ensure that the dynamic brake
resistor’s wattage rating is not exceeded. In general, values less than 90% are not
needed. This parameter’s setting is especially important if Parameter 182 (DB Resistor
Sel) is set to “2” (No Protection).
