Description
Enables the start inhibit function. The function prevents drive
restart (i.e. protects against unexpected start) if
• the drive trips on a fault and the fault is reset,
• the run enable signal is activated while the start command is
active (see parameter 10.11 Run
• control changes from local to remote, or
• external control switches from EXT1 to EXT2 or vice versa.
A new rising edge of the start command is needed after the
start inhibit has been activated.
Note that in certain applications it is necessary to allow the
drive to restart.
The start inhibit function is disabled.
The start inhibit function is enabled.
Defines how the start interlock input (DIIL) on the JCU control
unit affects the drive operation.
With the drive running:
• 1 = Normal operation.
• 0 = Stop by coasting. The drive can be restarted by
restoring the start interlock signal and switching the start
signal from 0 to 1.
With the drive stopped:
• 1 = Starting allowed.
• 0 = Starting not allowed.
With the drive running:
• 1 = Normal operation.
• 0 = Stop by ramping. The deceleration time is defined by
parameter 22.12 Em stop
by restoring the start interlock signal and switching the
start signal from 0 to 1.
With the drive stopped:
• 1 = Starting allowed.
• 0 = Starting not allowed.

• With permanent magnet motors and synchronous
reluctance motors, Automatic
The drive pre-magnetizes the motor before start. The pre-
magnetizing time is determined automatically, being typically
200 ms to 2 s depending on motor size. This mode should be
selected if a high break-away torque is required.
Note: This parameter cannot be changed while the drive is
