User Manual EM303B General Purpose Inverter Pre-excitation is for motor magnetic field set-up. The default can meet the needs. User does not need to change the defaults on general conditions. F5-31 Tmax indicates the maximum setting torque permitted by inverter. Range of Tmax: 50.00% ～ 250.00%. 8.7 C0 Group: Parameters of Monitoring Function When EM303B is running, operation parameters can be acquired by checking monitoring parameters in Group C0. All monitoring parameters are read only. When inverter is running, F4-20 defines the default of displayed monitoring parameter. The display of motor rotating direction can be set when monitoring frequency.
