TR150 Programming Guide
Function:
Set holding current as a percentage of the rated
motor current IM,N 1-24 Motor Current. 2-00 DC
Hold/Motor Preheat Current holds the motor
function (holding torque) or pre-heats the motor.
This parameter is active if DC hold is selected in
1-72 Start Function [0] or 1-80 Function at Stop [1].
Function:
Set current as % of rated motor current,
1-24 Motor Current. DC brake current is applied
on stop command, when speed is below the
limit set in 2-04 DC Brake Cut In Speed; when the
DC Brake Inverse function is active; or via the
serial port. See 2-02 DC Braking Time for duration.
Function:
in 2-01 DC Brake Current, once activated.
Function:
This parameter is for setting the DC brake cut
in speed at which the DC braking current
2-01 DC Brake Current is to be active, in
connection with a stop command.

2-17 Over-voltage Control
Option:
[0] Disabled No OVC required.
[2] Enabled Activates OVC.

NOTICE
The ramp time is automatically adjusted to
avoid tripping of the frequency converter.
BAS-SVP16A-EN - Rev. 2013-09-05
Function:
Set current as percentage of rated motor
current, 1-24 Motor Current. Active in
connection with 1-73 Flying Start. The parking
current is active during the time period set in
2-07 Parking Time.
NOTICE
2-06 Parking Current is only active when
PM motor construction is selected in
1-10 Motor Construction
Function:
Set the duration of the parking current time set
in 2-06 Parking Current. Active in connection with
1-73 Flying Start.
NOTICE
2-07 Parking Time is only active when PM
motor construction is selected in
1-10 Motor Construction
Function:
No brake resistor installed.
AC brake is active.
Function:
when using AC brake to avoid
overheating of motor windings.
Function:
Select whether to enable OVC, which reduces the
risk of drive trip due to over voltage on the DC
link caused by generative power from load.
