Parallel Drive Parameters
Contact factory for availability.
Drive ID [Drive ID]
Linear Number: 716
Default Value: 0
Minimum Value: 0
Maximum Value: 7
Access Level: Advanced
Read/Write: Read/Write when Stopped
This parameter specifies the identity of an individual drive in a parallel drive system. All drives in a
system should have unique ID numbers. If two drives are programmed with the same ID number, the first
drive to be powered up will take ownership of the ID number and the other drive will be dropped off the
Drive Area Network. Drive ID numbers do not have to be consecutive, there can be gaps in the
sequence (e.g. 0, 1, 3). Usually, Drive ID numbers cannot be freely assigned but are predetermined by
the node addresses of the system controller (PLC).
Power Up Configuration [Powerup Config]
Linear Number: 717
Default Value: Single Drive
Access Level: Advanced
Read/Write: Read/Write
This parameter defines the role that the drive will assume when the control is powered up.
Single Drive Drive not part of a parallel drive system-default
Master Master drive in a parallel drive system
Slave Slave drive in a parallel drive system
If more than one drive in a parallel drive system is programmed as Master, the first drive to be powered
up will become the master and the other drives will become slaves.
Master Mask [Master Mask]
Linear Number: 718
Default Value: 11111111
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies which drives in a parallel drive system are allowed to become master. A value
of 1 indicates that the corresponding drive can become master if required. A value of 0 indicates that the
corresponding drive will refuse to take on the role of master. Eight bits are defined:
Bit Enum Text Description
0 Drive 0 Drive 0 is selected to become master if required
1 Drive 1 Drive 1 is selected to become master if required
2 Drive 2 Drive 2 is selected to become master if required
3 Drive 3 Drive 3 is selected to become master if required
4 Drive 4 Drive 4 is selected to become master if required
5 Drive 5 Drive 5 is selected to become master if required
6 Drive 6 Drive 6 is selected to become master if required
7 Drive 7 Drive 7 is selected to become master if required
