 Connecting between Master and Slave Drives
• Connection Using External Analog Inputs and Outputs
Connect the Load Share outputs of the master drive (terminals FM and AM) to the analog
input terminals of the slave drive (terminals A1, A2, or A3). Example: The following diagram
shows the input connections from terminals FM and AM to terminals A1 and A3.
