 | Using HV DC bus sharing via VP and VN terminals or supplying external DC voltage to them, renders the safe torque off STO1 input unusable because STO1 is based on by cutting the AC supply. In order to preserve STO1 functionality with DC bus sharing, the STO1 signal must be fed simultaneously to all DC bus sharing drives. If an external DC supply is used (no AC input to L & N), then STO1 will not operate. STO1 will also be inoperable if DC voltage is supplied to L & N inputs instead of AC. With DC supply, STO1 ibput must be always powered as the internal relay may damage if STO1 used with DC supply. |
