OperationAnalog Input Calculate Function –  The inverter can mathematically combine two input 
sources into one value. The Calc ulate function can either add, subtract,  or multiply the two 
selected sources. This provides the flexibility  needed by various applications.You can use the 
result for the output frequency setting (use  A001=10) or for the PID Process Variable (PV) 
input (use A075=03).

“B” Group: Fine-Tuning Functions
The “B” Group of functions and parameters adjust  some of the more subtle but useful aspects 
of motor control and system configuration.
Automatic 
Restart Mode and 
Phase LossThe restart mode determines how the inverter will resume operation after a fault causes a trip 
event. The four options provide advantages fo r various situations. Frequency matching allows 
the inverter to read the motor speed by virtue of  its residual magnetic flux and restart the output 
at the corresponding frequency. The inverter can attempt a restart a certain number of times 
depending on the particular trip event:
 Over-current trip, restart up to 3 times
 Over-voltage trip, restart up to 3 times
 Under-voltage trip, restart up to 16 times
When the inverter reaches the maximum number of  restarts (3 or 16), you must power-cycle the 
inverter to reset its operation.
Other parameters specify the allowable under-voltage level and the delay time before restarting. 
The proper settings depend on th e typical fault conditions for your  application, the necessity of 
restarting the process in unattended situations, and whether re starting is always safe.

Electronic 
Thermal Overload 
Alarm SettingThe thermal overload detection protects 
the inverter and motor from overheating 
due to an excessive load. It uses a current/
inverse time curve to determine the trip 
point. The thermal overload alarm [THM] 
is the resulting intelligent output.
First, use B013 to select the torque 
characteristic that matches your load. 
This allows the inverter to utilize the best 
thermal overload characteristic for your 
application.
The torque developed in a motor is 
directly proportional to the current in the 
windings, which is also proporti onal to the heat generated (and temperature, over time). There-
fore, you must set the thermal overload threshold in terms of current (amperes) with parameter 
B012. The range is 50% to 120% of the rated curr ent for each inverter model. If the current 
exceeds the level you specify, the inverter will trip and log an event (error E05) in the history 
table. The inverter turns the motor output OFF when tripped. Separate settings are available for 
the second and third motors (if applicable), as shown in the table below.
Example 1, setting for SJ700-110LFE2 (0.4 to  55kW) - The rated motor current is 64A. The 
setting range is (0.2 * 64) to rated current, or 12.8A to 64.0A. For a setting of B012 = 64A 
(current at 100% rated curren t), the curve is shown below.
Example 2, setting for SJ700-750LFE2 (75 to 150 kW) - The rated motor current is 149A. The 
setting range is (0.2 * 149) to rated current, or 29.8A to 149A. For a setting of B012 = 149A 
(current at 100% rated curren t), the curve is shown below.

Example 3, setting for SJ700-3150LFE2 (185 to 
400kW) - The rated motor current is 600A. The 
setting range is (0.2 * 64)  to rated current, or 120A 
to 600A. For a setting of  B012 = 600A (current at 
100% rated current), the curve is shown to the 
right.
The electronic thermal characteristic adjusts the 
way the inverter calculates thermal heating, based 
on the type of load connected to the motor, as set 
by parameter B013.
CAUTION:  When the motor runs at lower 
speeds, the cooling effect of the motor’s internal 
fan decreases.
The table below shows the torque profile settings. 
Use the one that matches your load.
Reduced Torque Characteristic  – The 
example below shows the effect of the 
reduced torque characteristic curve (for 
example motor and current rating). At 20Hz, 
the output current is reduced by a factor of 
0.8 for given trip times.

Overload
RestrictionIf the inverter’s output current exceeds a 
preset current level you specify during 
acceleration or constant speed, the 
overload restriction feature automati-
cally reduces the ou tput frequency to 
restrict the overload. This feature does 
not generate an alarm or trip event. You 
can instruct the inverter to apply 
overload restriction only during 
constant speed, thus allowing higher 
currents for acceleration. Or, you may 
use the same threshold for both acceler-
ation and constant speed. In the case of 
controlled deceleration, the inve rter monitors both output current and DC bus voltage. The 
inverter will increase output frequency to try to  avoid a trip due to over-current or over-voltage 
(due to regeneration).
When the inverter detects an overload, it must de celerate the motor to reduce the current until it 
is less than the threshold. You can choose the rate of deceleration that the inverter uses to lower 
the output current.
