RDC6332NM switches to manual mode, and the Z-axis motor remains stationary

1. After pressing the switch, observe whether the contacts of the relay are correctly engaged. If the contacts switch normally, it indicates that the switching function is normal
2. First, test without enabling the hardware limit. If the machine can move normally, it indicates that the limit polarity is set incorrectly.
3. The Z-axis format can be set to a larger value, such as 10000
4. Set the motion mode to continuous motion mode (with a jog distance of 0) and test if the motion is normal

Perhaps the Z-axis format is set too small

I think you failed to switch the relay.
