MOTOR OVERHEATING
The maximum value depends on the rated
motor current.
To avoid motor damage caused by
overheating, do not run at 100% for too

MOTOR OVERHEATING
]
The maximum value depends on the rated
motor current.
To avoid motor damage caused by
overheating, do not run at 100% for too
long.
Set current as % of rated motor current,
parameter 1-24 Motor Current. When speed is
below the limit set in parameter 2-04 DC Brake Cut
In Speed, or when the DC-brake inverse function is
active (in parameter group 5-1* Digital Inputs set to
[5] DC-brake inverse; or via the serial port), a DC-
brake current is applied on a stop command. See
parameter 2-02 DC Braking Time for duration.
2-02 DC Braking Time
Range: Function:
10 s [0 - 60 s] Set the duration of the DC-brake current set in
*
parameter 2-01 DC Brake Current, once
activated.

with parameter 1-73 Flying Start. The parking
current is active during the time period set in
parameter 2-07 Parking Time.
NOTICE
Parameter 2-06 Parking Current is only
active when 1 of the PM motor
construction options is selected in
parameter 1-10 Motor Construction.
2-07 Parking Time
Range: Function:
3 s [0.1 - 60 Set the duration of the parking current time set

s] in parameter 2-06 Parking Current. Active with
parameter 1-73 Flying Start.
NOTICE
Parameter 2-07 Parking Time is only active
when options of parameter 1-10 Motor
Construction are set to enable PM motors.
