RUN
1 MIN1 SP= 0%
SPEED MIN LIMIT1
G10.1 / Minimum
speed limit 1
-250% to
Max speed 1
This sets the minimum speed limit 1 that can be applied to the motor by the drive.
It is set in percentage of motor rated speed.
YES
2 MAX1 SP=+100%
SPEED MAX LIMIT1
G10.2 /
Maximum speed
limit 1
Min. speed 1
to +250%
This sets the maximum speed limit 1 that can be applied to the motor by the drive.
If the reference is higher than the value set in this parameter, the drive will ignore
that reference and will operate the motor at the value set in this screen.
It is set in percentage of motor rated speed.
YES
3 MIN2 SP=-100%
SPEED MIN LIMIT2
G10.3 / Minimum
speed limit 2
-250% to
Max speed 2
This sets the minimum speed limit 2 that can be applied to the motor by the drive.
It is set in percentage of motor rated speed.
Note: Selection of minimum speed limit 2 is done via a digital input or comparator
output function.
YES
4 MAX2 SP=+100%
SPEED MAX LIMIT2
G10.4 /
Maximum speed
limit 2
Min. speed 2
to +250%
This sets the maximum speed limit 2 that can be applied to the motor by the drive.
If the reference is higher than the value set in this parameter, the drive will ignore
that reference and will operate the motor at the value set in this screen.
It is set in percentage of motor rated speed.
YES
5 I LIMIT=___A (*)
MAX CURRENT
G10.5 / Current
limit
0.25 to
1.50In,
OFF
Output current limit. Motor current will be within this programmed limit. When this
protection is active the SD700 status of current limitation (ILT) is displayed.
Note: We do not recommend that current limit works constantly in applications
when the motor is at steady speed status. Damage may occur to the motor and
torque variations can affect the load. Current limit should work only when an
overload occurs, or due to excessive acceleration and deceleration values, or
because motor data details are entered incorrectly.
YES
6 I LIM TO= OFF
TIMOUT MAX CURRE
G10.6 / Trip time
because of
current limit
0 to 60s,
OFF
If the drive is operated continually at current limit for the time set in this screen the
drive generates a fault.
YES
7 I. MAX2=____A (*)
MAX CURRENT 2
G10.7 /
Alternative
current limit
0.25 to
1.50In,
OFF
This limit operates with the same philosophy as G10.5, but for the second current
limit.
YES
8 MI2 brSP=OFF
MAX CURR BRK SPD
G10.8 / Change
speed for Imax 2
OFF=0%,
+1 to +250%
It allows setting the speed level to change from current limit 1 to current limit 2.
Additionally, it is possible to select the alternative current limit 2 using a digital
input configured as option 23.
YES
9 MAX TOR=+150%
MAX TORQUE
G10.9 / Torque
limit
0% to
+250%
This value is the maximum motor torque the drive will allow the motor to supply to
the load. It is set in percentage of motor rated torque.
YES
10 T LIM TO=OFF
TIMEOUT MAX TORQ
G10.10 / Trip
time because of
torque limit
0 to 60s,
OFF
If the drive is operated continually at torque limit for the time set in this screen the
drive generates a fault.
YES
11 INVERSION ?=N
G10.11 / To
enable speed
inversion
N
Y
The drive can be configured to prevent the motor running in negative direction.
OPT.
FUNCTION
N=NO
Motor running in negative rotation direction is not
allowed.
Y=YES
Motor running in both rotation directions is
allowed.
YES
12 ILIM RGN=OFF
CURR.LIMIT.RGN
G10.12 /
Regenerating
current limit
OFF = 40%·In
(motor),
40.1% to
200%·In
(drive)
Output current limit during regeneration. It keeps the motor load current within the
adjusted limit during regeneration. When this protection is active, the display
shows that the SD700 is limiting current (ILT).
If this parameter is set to ‘OFF’, the algorithm is not enabled.
YES
13 Ilim_rgnTO=OFF
ILim.Regen.Tmout
G10.13 /
Regenerating
current limit trip
time
0 to 60s,
OFF
It allows setting the trip time once the current limit is reached.
YES
14 T/I LIM SP = N
G10.14 / Torque
limit algorithm
N
Y
It allows disabling of the torque/current limit algorithm.
OPT.
FUNCTION
N=NO
Algorithm is enable. By limiting the current or the
torque, the equipment reduces its speed.
Y=YES
Algorithm is disable but the equipment still using
current or torque limit (G10.5 and G10.9) and
timeouts (G10.6 and G10.10) which could mean
drive trip.
YES
15 Rg TQ L = 150%
G10.15 / Torque
limit range
0 to 250%
It allows limiting the regenerative torque of the motor.
YES
 This value depends on the drive rating.
