Hello to everyone, I have a question regarding Holding brake control in G120C PN drive. I have followed the instructions from manual and assigned DO1 (relay output) to control opening and closing of the holding brake (r52.12 routed to DO1). The problem is the DO1 output is always ON whenever the drive is powered and there is no fault present (i.e. 3 input phases are present and no matter the state of OFF1, OFF2, OFF3 control word bits DO1 is ON). Status word bit 12 (holding brake open) is always on. I can start the motor through Control Word at any moment. STO function is not used. Pictures of parameters attached. What might be the problem? Should r899.12 be connected to DO1 instead of r52.12? Could it be the firmware issue? Attachmentsinam.zip (134 Downloads) |

Hello, In case of motor holding brake p1215 must be set to 3 & r0899.12 should be interconnected as control signal. For more details, refer attached FD sheet. HTH AttachmentG120C motor holding brake.pdf (780 Downloads) |
