30:PID integral reset
Closed = Set integrator value to 0.
31: PID integral hold
Closed = Hold integrator at its present level.
32: Multi-Step Reference 4
Based on the status of Multi-Step Reference 1 to 4 (d1-16).
34: PID Soft Starter Cancel
Closed = b5-17 is ignored.
35: PID Input (Error) Polarity Change
Closed = PID error signal polarity is reversed (1 to -1 or
-1 to 1).
60: DC Injection Braking
Closed = Apply DC injection current as set in parameter b2-02.
61: Speed Search 1
Closed = While a run command is given, Drive does a speed
search starting at maximum frequency (E1-04). Speed search
based on b3-01.
62: Speed Search 2
Closed = While a run command is given, Drive does a speed
search starting at frequency reference. Speed search based on
b3-01.
63: Field Weakening Command (Energy Savings)
Closed = Field weakening control set for d6-01 and d6-02.
64: Speed Search 3
Closed = And a run command is given, Drive does a speed
search starting at output frequency. Speed search based on
b3-01.
65: Kinetic Energy Braking Ride-thru N.C.
Closed = Normal operation
Open = KEB ride-thru is enabled.
66: Kinetic Energy Braking Ride-thru N.O.
Closed = KEB ride-thru is enabled.
67: Communications Test Mode
Used to test Modbus RS-485/422 interface.
68: High Slip Braking
Closed = Drive stops using High Slip Braking regardless of run
command status.
69: Jog 2
Closed = Drive runs at frequency reference entered into
parameter d1-17. Direction determined by fwd/rev input.
3-wire control Only.
6A: Drive Enable - Closed = Drive will accept run command.
Open = Drive will not run. If running, Drive will stop per
b1-03.
71: Speed / Torque Control Selection
Closed = Torque control operation.
Open = Speed control operation.
72: Zero-Servo Command
Closed = Zero-Servo ON
77: ASR Gain Switch
Closed = ASR proportional gain and integral time is set
according to C5-03 and C5-04.
78: Polarity Reversing Command for External Torque Control
Closed = Reverse polarity.
0 to 78
