2 = Para ID 2207: DI closed contact = start / open contact = stop Para ID 2208: DI closed contact = start
enabled / open contact = start disabled and drive stopped if running Motor direction keeps forward - This
would be considered 3 wire control with Start signal 2 required to be closed to enable Start on Start
signal 1.

3 = Three-wire connection (pulse control): Para ID 2207: DI changes from open to closed = start pulse Para
ID 2208: DI changes from closed to open = stop pulse Para ID 198: DI closed contact = reverse/ open
contact = forward - This would be considered 3 wire control with Start Signal 1 being the Start Pulse and
Start Signal 2 being the NC Stop.

IO Terminal 2 Start Signal 1
1,2,3
RW
The 2
nd
Signal selection 1 for the start/stop logic listed in parameter Para ID 2206. When the parameter is
set to DigIN: 1 it references DIN1 on the control board, selecting different DIGIN values will assign it to a
different input on the control board or option card. When set to Normally Open this function would be always
tied low or 0 when using I/O terminal 1 as the control place. When value is set to Normally Closed this will
cause the function to be always on and activate the output if I/O Terminal 1 is the current control place. Can
be set to DigiIN:X indicates on board terminal inputs, DigiIN:A:IOX:X indicates optional board inputs in A slot,
DigiIN:B:IOX:X indicates optional board inputs in B slot, or Timer Channel X

IO Terminal 2 Start Signal 2
1,2,3
RW
The 2
nd
Signal selection 2 for the start/stop logic listed in parameter Para ID 2206. When the parameter is
set to DigIN: 2 it references DIN2 on the control board, selecting different DIGIN values will assign it to a
different input on the control board or option card. When set to Normally Open this function would be always
tied low or 0 when using I/O terminal 1 as the control place. When value is set to Normally Closed this will
cause the function to be always on and activate the output if I/O Terminal 1 is the current control place. Can
be set to DigiIN:X indicates on board terminal inputs, DigiIN:A:IOX:X indicates optional board inputs in A slot,
DigiIN:B:IOX:X indicates optional board inputs in B slot, or Timer Channel X
P2.2.7

Thermistor Input Select
1,2,3
RW
This parameter defines DIN7, and DIN8 is digital input or thermistor input. When this parameter is enabled it
switches DIN7 and DIN8 to a thermistor input that triggers at 4.7k ohm.
P2.2.8
198
Reverse
1,2,3
RW
Use this parameter for switching the direction of the motor to reverse when using 3 wire start/stop logic
parameter in Para ID 143 = 3. Can be set to DigiIN:X indicates on board terminal inputs, DigiIN:A:IOX:X
indicates optional board inputs in A slot, DigiIN:B:IOX:X indicates optional board inputs in B slot, or Timer
Channel X
Contact Open = Forward direction.
Contact Close = Reverse direction.
