[DC Hold Time]
This value sets the amount of time that the
[DC Hold Level] voltage will be applied to the motor
when the stop mode is set to either
”DC Brake” or “Ramp.”
Important: Assure that [DC Hold Level] is set for a
value that is adequate for motor protection when
maximum DC hold is selected.
Parameter Number 12
Parameter Type Read and Write
Display Units / Drive Units 0.1 Second / Seconds x 10
Factory Default 0.0 Sec
Minimum Value 0.0 Sec
Maximum Value 1000 Sec
[DC Hold Level]
This value sets the DC voltage applied to the motor
to produce the selected current during braking,
when the stop mode is set to either “DC Brake” or
“Ramp.”
Parameter Number 13
Parameter Type Read and Write
Display Units / Drive Units 1 % of [Rated Amps] / 4096 = 100%
Factory Default 100 %
Minimum Value 0 %
Maximum Value 150 %
ATTENTION: If a hazard of injury due to movement of
equipment or material exists, an auxiliary mechanical braking
device must be used to stop the motor.
ATTENTION: This feature should not be used with
synchronous or permanent magnet motors. Motors may be
demagnetized during braking.

[Bus Limit En]
Enables the function that attempts to limit the drive
DC bus voltage to 110% of nominal voltage during
rapid decel. If bus voltage rises above the 110% level,
[BUS Limit En] reduces or stops the drive decel rate
until bus voltage falls below the 110% level.
Parameter Number 11
Parameter Type Read and Write
Factory Default “Disabled”
Units Display Drive
“Disabled” 0
Allow bus voltage to rise above
110%.
“Enabled” 1 Limit bus voltage/decel ramp.
[Motor Type]
This parameter should be set to match the type of
motor connected to the drive.
Parameter Number 41
Parameter Type Read and Write
Factory Default “Induction”
Units Display Drive
“Induction” 0
Requires no additional setting.
“Sync Reluc” 1 [Slip @ F.L.A.] must be set to zero.
“Sync PM” 2 [Stop Select 1 & 2] must be set to a
selection other than “DC Brake” and
[Slip @ F.L.A.] be set to zero.
