Overview of Motor Phase Current
NOTE:
LMD models without an encoder will operate in fixed run/hold current only.
The motor phase current of the drive is influenced by the following factors:
• The setting of the run current.
• The setting of the holding current.
• The setting of the holding current delay.
• The setting of the motor settling delay.
• Current control defined as fixed or variable.
Refer to the following graphic for an overview of motor phase current.

Software Operation Modes
The LMD is controlled and programmed using the MCode language which consists of 1 and 2
character mnemonics.

Immediate Mode (Streaming Command) - All Protocols
In Immediate Mode, the device will respond to streaming commands entered via the service
interface. If used solely in this mode, the device will operate as a slave in a master-slave
relationship with a communication host in a centralized control system.
In this mode, the device will respond to motion commands and queries for register data, read
the state of inputs, or set the state of outputs based upon instructions from the system master.
