1 MTR CURR=00.00A
G2.1 / Motor rated current
__A (Set according to motor nameplate).
2 MTR VOLT=400V
G2.2 / Motor rated voltage
__V (Set according to motor nameplate).
3 MTR PWR=00.0kW
G2.3 / Motor rated power
__kW (Set according to motor nameplate).
4 MTR RPM=1485
G2.4 / Motor rpm
__rpm (Set according to motor nameplate).
5 MTR PFA=0.85
G2.5 / Cosine Phi
__ (Set according to motor nameplate).
6 MTR FRQ=50Hz
G2.6 / Motor frequency
__Hz (Set according to motor nameplate).
7 MTR COOL=63%
G2.7 / Motor cooling at zero speed
Use the following values as a reference:
Submersible pumps and non-deflagrating motors  5%
Self-cool motor  63%
Force-cooled motor  100%
G3: References.
1 REF1 SPD=PMOT
G3.1 / Speed reference source 1
PMOT  Motorized potentiometer with or without reference
memory.
G4: Inputs – S4.1: Digital Inputs.
1 CNTROL MODE1=2
G4.1.1 / Main Control Mode
2  REMOTE (Drive control is done through control terminals).

G4.1.4 / Digital Inputs configuration
selection
4  MOTORIZED POT (It assigns the function of up and down
speed reference to two of the digital inputs. DI5 = Up (NO Contact)
and DI6 = Down (NC Contact). Reference is memorized)
5  ERASAB POT (As per above mode without memorizing the
reference).
5 DIGITL IN 1=05
G4.1.5 / Multi-function Digital Input 1
configuration
05  Start/Stop (Allows the start/stop command to be given by a
switch).
G5: Inputs: Acceleration and Deceleration Ramps.
7 PMT ACL1=1.0% / s
G5.7 / Ramp 1 of reference increase for
motorized potentiometer
1.0% / s (Modify these ramps to tune operation). If the ramp is
increased the speed reference response will be faster. If the ramp
is decreased the speed reference response will be slower.
8 PMT DCL1=3.0% / s
G5.8 / Ramp 1 of reference decrease for
motorized potentiometer
3.0% / s (Modify these ramps to tune operation). If the ramp is
increased the speed reference response will be faster. If the ramp
is decreased the speed reference response will be slower.
7.3.2. Connections Drawing
Terminals 1 and 2: start / stop command (NO status).
Terminals 1 and 6: up speed command (NO status).
Terminals 1 and 7: down speed command (NC status).
