5.5 MOTOR CONFIGURATION
In order to achieve an efficient motor protection, it is necessary to configure the parameters correctly according
to the motor data.
P295 – Current and/or Voltage Measurement Unit (UMC/UMCT)
Adjustable
Range:
0 = UMC0/UMCT0 (0.25 – 2.5 A)
1 = UMC1/UMCT1 (0.5 – 5 A)
2 = UMC2/UMCT2 (1.25 – 12.5 A)
3 = UMC3/UMCT3 (2.5 – 25 A)
4 = UMC4/UMCT4 (12.5 – 125 A)
5 = UMC5/UMCT5 (42 – 420 A)
6 = UMC6/UMCT6 (84 – 840 A)
7 = UMC1/UMCT1 + TC externo

Proprieties: Sys, CFG
Description:
It selects the Current Measurement Unit (UMC) or Current/Voltage Measurement Unit (UMCT) that will be
connected to the SRW 01. For more information refer to the
Section 3.5 CURRENT MEASUREMENT UNIT (UMC)
CONNECTION on page 3-5 and Section 3.6 CONNECTION OF THE CURRENT/VOLTAGE MEASUREMENT
UNIT (UMCT) on page 3-6 of this manual.
NOTE!
The Control Unit sends out a signal through the status led (red) and message “E0082” on the HMI if
the rated current of the motor (P401/P402) is out of the current measuring unit range. In this condition,
it does not allow the motor to be driven while there is an error condition and automatically leaves the
error condition when the setting is valid. There is no need for the reset control. A signal is sent out
through the status led (green) and the message “E0082” on the HMI is cleaned.
