Using Multi-Drive Mode Chapter 7
The following Multi-drive parameters must be set in the master PowerFlex 525
drive:
Using Multi-Drive Add-On
Profile
Before using the Multi-drive Add-On Profile, ensure that you have completed the
following steps:
• The master and daisy-chained drives are powered, networked, and
configured. See System Wiring
on page 85.
• The RS-485 network is configured. See Configuring the RS-485 Network
on page 86.
• The controller has been added to the I/O configuration. See Adding the
Controller to the I/O Configuration on page 38.
Adding the Drive to the I/O Configuration
To transmit data between the controller and the drive, you must add the drive as a
child device to the parent controller. In this example, RSLogix 5000 version 20 is
used with drive Add-On Profile version 1.01 or later.
Parameters [Comm Loss Action] and [Comm Loss Time] in the daisy-chained
drives are still used in Multi-drive mode. If the RS-485 cable is disconnected or
broken, the disconnected drive(s) will take the corresponding Comm Loss
Action(s). On the EtherNet/ IP side, parameters C143 [EN Comm Flt Actn] and
C144 [EN Idle Flt Actn] determine the action taken for ALL of the drives on the
Multi-drive node.
Parameter Value
P046 [Start Source 1] 5 “EtherNet/IP”
P047 [Speed Reference1] 15 “EtherNet/IP”
C169 [MultiDrv Sel] 0 “Disabled”
1 “Network Opt”
2 “EtherNet/IP”
Note: Drive must be power cycled after setting this
parameter.
C171 [Drv 1 Addr] C124 [RS485 Node Addr] in Drive 1
C172 [Drv 2 Addr] C124 [RS485 Node Addr] in Drive 2
C173 [Drv 3 Addr] C124 [RS485 Node Addr] in Drive 3
C174 [Drv 4 Addr] C124 [RS485 Node Addr] in Drive 4
C175 [DSI I/O Cfg] 0 “Drive 0”
1 “Drive 0-1”
2 “Drive 0-2”
3 “Drive 0-3”
4 “Drive 0-4”
Parameters can be set using a DSI peripheral (22-HIM-A3 or 22-HIM-C2S) only
when parameter C169 [MultiDrv Sel] is set to 0 “Disabled”.
