Hello All,
I have Powerflex 525 drive running over Ethernet IP. The system is running for quite some time. Every now and then we have a strange issue. When the start command is given the drive doesn’t move. I have the checked the drive paramters the commanded frequency is 50 hz but output frequency and voltage is 0.I have checked voltage across terminal 1 it has 24v dc and also the control status bit 1 confirms that. I have checked 24 V dc at s1 and S2 terminals. The only way to run the drive is toggle safety input of s1 and s2 and the drive runs. What could be the reason. Kindly advice
