LIMITS
(Continued)
MAXIMUM START CURRENT
ENABLE
(30.15)
Default: 0 (Disable)
Range: 0, 1
0 (Disable) Start current limit disabled
1 (Enable) Start current limit enabled
A temporary motor current limit specifically for starting can be defined
by this parameter and 30.16 Maximum start current.
When this parameter is set to Enable, the drive observes the start
current limit defined by 30.16 Maximum start current.
The limit is in force for 2 seconds after initial magnetization (of an
asynchronous induction motor) or autophasing (of a permanent
magnet motor), but not more often than once in every 7 seconds.
Otherwise, the limit defined by 30.17 Maximum current is in force.
Note:
The availability of a start current higher than the general limit
depends on drive hardware.
MAXIMUM CURRENT (30.17) Default: 120% of rated current
Range: 0.00 to 30000.00 A
Sets the maximum allowed motor current; set to 120% of 99.06 motor
nominal current.
MAXIMUM TORQUE
(30.31) Default: 1 (Enable)
Range: 0, 1
0 (Disable) Undervoltage control disabled
1 (Enable) Undervoltage control enabled
Enables the undervoltage control of the intermediate DC link. If the DC
voltage drops due to input power cut off, the undervoltage controller
will automatically decrease the motor torque in order to keep the
voltage above the lower limit. By decreasing the motor torque, the
inertia of the load will cause regeneration back to the drive, keeping
the DC link charged and preventing an undervoltage trip until the
motor coasts to a stop. This will act as a power-loss ride-through
functionality in systems with high inertia, such as a centrifuge or a fan.
FAULT
FUNCTIONS
Configuration of external events; selection of behavior of the drive upon fault situations.
