Description

Default
STARTUP CURRENT
MOTOR2
This parameter is used in conjunction with the ENABLE STARTUP
parameter. It selects the current level during the startup procedure used
for starting motors with a high inertia and/or friction load.
The percentage value is a percentage of the nominal motor current (I0 of
the PMAC MOTOR function block)
This value cannot be higher than 150% of the drive rating.
The default value of 10% is considered appropriate for most
applications.
0 to 200%
10%
STARTUP SPEED
MOTOR2
This parameter is used in conjunction with the ENABLE STARTUP
parameter. It selects the speed setpoint at which the speed control is
switched from an open loop mode to a closed loop mode during the
startup procedure used for starting motors with a high inertia and/or
friction load..
The percentage value is a percentage of the maximum application speed
(MAX SPEED of the REFERENCE function block )
In open loop mode, the system is not controlled in speed mode. It must
only be used to ‘start’ the motor under heavy conditions, or to transitorily
reach the zero speed or crossing the zero speed setpoint. It is not
intended to be used to control accurately a motion.
0 to 100%
5%

AIMING POINT
Determines the final level of the inverse time current limit after a period
of prolonged motor overload.
50 to 150%
105%
DELAY
Determines the maximum overload duration before inverse time current
limit action is taken
5 to 60s
30s
DOWN TIME
Determines the rate at which the inverse time current limit is ramped
down to the AIMING POINT after a period of prolonged overload.
1 to 10s
1s
UP TIME
Determines the rate at which the inverse time current limit is ramped
back to the maximum current.
0.5 to 100s
1s
IT LIMITING
This diagnostic indicates if the drive protection is active.
0=FALSE
1=TRUE
INV TIME OP
This diagnostic indicates the actual current level limit.
---%
IT WARNING
This diagnostic indicates that the drive will reach its maximum overload
level.
0=FALSE
1=TRUE
