EVCO S.p.A. EVDRIVE03 | User manual ver. 3.4 | Code 144EPDE344 6 OPERATION 6.1 Switch on and resynchronization At switch-on and after a resynchronization, the fundamental parameters for moving the motor are acquired. The parameters of pressure and temperature units of measure are loaded at switch-on, and, if necessary, is performed the conversion of all the parameters of pressure and temperature.
EVCO S.p.A. EVDRIVE03 | User manual ver. 3.4 | Code 144EPDE344 The positioning speed depends on the operation mode: - during resynchronization is used the maximum speed, but towards the end of the positioning is made a deceleration ramp - in debug mode is used the speed of the Debug step rate (parameter Prd0) - in manual mode and for all other positioning is used the maximum speed. Using Limit valve opening (parameter Pr30) it is possible to adapt the valve to the application.
