Dear sir In dc drive we have to set Field control mode it can be voltage control and current control so can you explain on which basis we can select this modes and what will happen by selecting field voltage control and field current control modes.
Field current is reduced to increase the motor speed above base speed this is called "Constant HP" when we need high speed and lower torque then field current is decreased upto minimum field current written on motor name plate in separately exited DC motors.
1)Set multimeter at DC mA 2)Open one wire of mA where you want to measure 3) Connect multimeter's 1 laed in wire you removed and 2lead at that place from where you removed the wire.
Very nice explain and knowledge video
Thank you sir. valuable information
Nice explanation
Very nice explain and informative

where dual speed motors are used for winder /unwinder like applications this method is used.
Sir how can we measure mili Amp in plc? We are not sure if we are getting output out of PLC.
1)Set multimeter at DC mA
2)Open one wire of mA where you want to measure
3) Connect multimeter's 1 laed in wire you removed and 2lead at that place from where you removed the wire.
multimeter should be connected in series

Hello sir i need your help please
My dc drive model etd 791
Isme Field Error show kar rahahe
I need your suggestion please sir
Please check Mains Input fuse, field power fuse if present, field winding resistance and megger,field power cable..
@@aforautomation field coil resistance 8 ohm
Fuse sab oky he
Cabel change karke dekha
But nehi horaha he
@@rakibtechzone174 replace field card
If problem still there replace CPU or motherboard
