G2.2
/ Motor
rated voltage
220 – 999V
400V
It allows setting of the motor rated voltage according to its
nameplate.

6 MTR FRQ=50Hz
MOTOR FREQUENCY
G2.6
/ Motor
rated frequency
0 – 100Hz
50Hz
It allows setting of the motor rated frequency according to its

YES
7 MTR COOLN=40%
MOTOR COOLING
G2.7
/ Motor
cooling at zero
speed
OFF,
20 – 100%
40%
It provides adjustment of sensitive of the motor thermal model
based on actual motor cooling.
The following settings can be taken as reference:
Submersible pumps
Î
20%
Self-cool motor
Î
40%
Forced-cool motor
Î
100%
Note:
If the drive is working at low speeds for a long time and
several trips caused by motor thermal model are produced even
though the motor was not hot then this value can be increased
slightly to avoid further tripping.
Note:
If it is set to 'OFF', thermal model will be deactivated.
YES

NONE
Reference source 1 has not been selected.
AI1
Reference will be introduced through the
Analogue Input 1.
AI2
Reference will be introduced through the
Analogue Input 2.
AI1+AI2
Reference will be the sum of the signals
introduced through the Analogue Inputs 1 and 2.
RES Reserve
LOCAL
Reference will be given by keypad and will be set
in ‘G3.3'Local Speed Reference'.
MREF
Multi-Reference. Different references activated by
the digital inputs. It will be necessary to configure
the digital inputs. See ‘S4.1
Î
Digital Inputs’.
PMOT
Motorized potentiometer with or without reference
memory.
PID
It will take as reference the value set in the
parameters of the PID function.
YES
∗
This value depends on the drive rated current.
Note:
If all of these values are not entered correctly, the SD700 will not operate correctly. When the motor nameplate
offers multiple configuration possibilities, as in case of the start-delta motor connection, ensure the correct data is
entered for the appropriate configuration.
