I don't have the NI-CAN drivers installed, so I can't analyse your VI completly, but my first guess would be, that the CAN Interface of your second Lenze drive is not configured correctly. Your first Lenze drive has 1473 as Send-ID for the CAN and 1601 as Receive ID for the CAN. To control the second Lenze drive you have to configure it with different IDs and adjust the numbers in the VI accordingly.
A CAN interface/device only listens to the messages send with an CAN-ID that configured as receive ID in the interface/device. I hope this helps a little. Chris
