Emerson unidrive m200 - Stop Mode; Definition of Logic Symbols for Sequencer Logic Diagrams

Throughout this section reference is made to the sequencer bit parameters DriveEnable (06.015), RunForward (06.030), JogForward (06.031), RunReverse (06.032), Forward/Reverse
(06.033), Run (06.034), JogReverse (06.037) and NotStop (06.039). IfControlWordEnable (06.043) = 1 and bit 7 (Auto/manual) in the ControlWord (06.042) is 1 then the appropriate bits in
the control word are used instead.
Parameter 06.001 Stop Mode
Short description Defines how the motor is controlled when the run signal is removed from the drive
Mode Open‑loop
Minimum 0 Maximum 5
Default 1 Units
Type 8 Bit User Save Update Rate Background read
Display Format Standard Decimal Places 0
Coding RW, TE
Value Text Description
0 Coast Coast stop
1 rp Ramp Stop
2 rP.dcI Ramp stop + 1 second dc injection
3 dc I Injection braking stop with detection of zero speed
4 td.dcI Timed injection braking stop
5 diS Disable
Stopping is in two distinct phases as shown in the table below for each of the possible values of StopMode (06.001).
Stop Mode (06.001) Phase 1 Phase 2 Comments
0: Coast Inverter disabled Drive cannot be re-enabled for 1s Delay in phase 2 allows rotor flux to decay
1: Ramp Ramp down to zero frequency Wait for 1s with inverter enabled
2: Ramp followed by
d.c. injection
Ramp down to zero frequency
Inject d.c. at level defined by InjectionBrakingLevel
(06.006) for time defined by InjectionBrakingTime
(06.007)
3: D.c. injection with
zero frequency
detection
Low frequency current injection with detection of low
speed before next phase
Inject d.c. at level defined by InjectionBrakingLevel
(06.006) for time defined by InjectionBrakingTime
(06.007)
The drive automatically senses low speed and
adjusts the injection time to suit the application
4: Timed d.c. injection
stop
Inject d.c. at level defined by InjectionBrakingLevel
(06.006) for time defined by InjectionBrakingTime
(06.007)
Inject d.c. at level defined by InjectionBrakingLevel
(06.006) for 1s.
The minimum total injection time is 1s for phase
1 and 1s for phase 2, i.e. 2s in total.
5: Disable Inverter disabled No phase 2
Allows drive to be disabled then re-enabled
immediately
The following should be noted:
1. Once phase 1 has begun with StopMode (06.001) = 3 or 4 the stopping sequence must be completed or terminated by de-activating the Final drive enable or because the drive has
tripped.
2. If StopMode (06.001) = 5 the drive can be disabled and re-enabled immediately if the Final drive run is de-activated to stop the drive. If the Final drive enable is used to stop the drive
then there is a 1s delay before the drive can be re-enabled.
