Parameters 115
10.17 Start enable Selects the source for the start enable signal.
1 = Start enable.
If the signal is switched off, the drive will not start or coasts to
stop if running.
DI1 Digital input DI1 (as indicated by 02.01 DI status, bit 0). 1073742337
DI2 Digital input DI2 (as indicated by 02.01 DI status, bit 1). 1073807873
DI3 Digital input DI3 (as indicated by 02.01 DI status, bit 2). 1073873409
DI4 Digital input DI4 (as indicated by 02.01 DI status, bit 3). 1073938945
DI5 Digital input DI5 (as indicated by 02.01 DI status, bit 4). 1074004481
DI6 Digital input DI6 (as indicated by 02.01 DI status, bit 5). 1074070017
DIO4 Digital input/output DIO4 (as indicated by 02.03 DIO status,
bit 3).
1073938947
DIO5 Digital input/output DIO5 (as indicated by 02.03 DIO status,
bit 4).
1074004483
DIO6 Digital input/output DIO6 (as indicated by 02.03 DIO status,
bit 5).
1074070019

10.19 Start inhibit 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 enable),
• control changes from local to remote, or
• external control switches from EXT1 to EXT2 or vice versa.
An active start inhibit can be reset with a stop command.
Note that in certain applications it is necessary to allow the
drive to restart.
Disabled The start inhibit function is disabled. 0
Enabled The start inhibit function is enabled. 1
10.20 Start interl func Defines how the start interlock input (DIIL) on the JCU control
unit affects the drive operation.
Off2 stop 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.
0
Off3 stop With the drive running:
• 1 = Normal operation.
• 0 = Stop by ramping. The deceleration time is defined by
parameter 22.12 Em stop time. 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.
