It generates the gate-firing pulses that control the thyristors during motor acceleration and deceleration, so a failed board means the soft starter won't start the motor — no ramp, no bypass. If you're holding a 3RW44 Size 2 with a dead firing section, this is the board that goes back in.","metaTitle":"Siemens 3RW4727-0VC70 Firing PCB for 3RW44 Size 2","metaDescription":"Siemens 3RW4727-0VC70 firing PCB for 3RW44 soft starter Size 2.
