Understanding the 2-Wire Control Types
Transition Control
- The drive must be powered up before a run command is issued.
- If a run input is already active when power is applied, the drive will not start until the command is cycled.
Level Control
- The drive starts whenever a valid run command is present.
- If the run command remains active during power-up, the drive will automatically start when power is restored.
- If no run command is active, the drive remains in RDY (Ready) status until a run command is received.
Important Safety Notice:
Level Control may cause the motor to restart automatically after a power cycle or power restoration if the run command remains active. Verify that this behavior is safe and appropriate for your application before enabling this control mode.
