10.6 Stop conditions, Digital Inputs and Hardware Limit Switches
10.6.1 Turning on the drive
Turning on the drive is only possible, if it has passed the self-test on startup
successfully. Otherwise it will be stuck at the DS402 state "Not ready to switch on".
Then the status bits 2
6
= "Switch-on disabled" and/or 2
9
= "Remote" are 0.
If a fault has occurred, it must be cleared before turning on the drive. If there are
hardware failures or invalid parameters, that however must be fixed first. Otherwise
the fault will immediately occur again.
"Control word" 0x6040 = 0x0000
-> "Status word" 0x6041 = 0x0648 // switch on disabled, fault
"Control word" 0x6040 = 0x0080
-> "Status word" 0x6041 = 0x0640 // switch on disabled, fault cleared
This sequence enables the operation and turns on the motor:
"Control word" 0x6040 = 0x0000
-> "Status word" 0x6041 = 0x0640 // switch on disabled, fault
"Control word" 0x6040 = 0x0006
-> "Status word" 0x6041 = 0x0621 // ready to switch on
"Control word" 0x6040 = 0x000F
-> "Status word" 0x6041 = 0x0637 // operation enabled
10.6.2 Stop conditions: Priorities, Behavior
If the drive has been turned on and thus has reached the DS402 state "Operation
enabled", stop conditions can be triggered by the following events. This list is sorted
by the priorities, and the highest comes first:
By a hardware failure, which causes a fatal fault. The drive goes to the DS402
state "Fault" and immediately switches off the motor.
This state can be left only by a rising edge on the control word bit 2
7
.
By clearing the control word bit 2
1
and turning the motor voltage off.
The drive goes to the DS402 state "Switch-on Disabled" and immediately switches
off the motor.
By a non-fatal fault, that may be the result of hardware failures or of invalid
parameters.
The drive goes to the DS402 state "Fault Reaction Active", stops, then goes to the
DS402 state "Fault" and switches off the motor. The reaction is selected by its
option code 0x605E:
0 -> Immediately turn off the drive
1 -> Slow down at the "Profile Deceleration" 0x6084 before turning off the drive.
0xC001 -> Slow down at the "Homing Acceleration" 0x609A before turning off the
drive.
2 or any other value -> Slow down at the "Quick stop Deceleration" 0x6085 before
turning off the drive.
