650 Series AC Drive
Configuring Terminal 10 (Digital Input/Output)
Terminal 10 can be operated as digital input DIN4 or digital output DOUT2.
Configure for use as DIN4 (default)
To use terminal 10 as an input, the output circuitry must be disabled by setting
S
OP21 and
S
OP22
to zero. You can invert this logic using parameter
S
IP04.

DIN4 INVERT
Default is 0, setting to 1 inverts the input logic
Configure for use as DOUT2
To use terminal 10 as an ouput, select
S
OP21 to be 1, 2, 3, 4 , 5 or 6. For example, you could set
parameter
S
OP31 to 3 to have the output go high (24V) whenever the motor is running. You
could use this to operate an external relay or lamp, for instance. You can invert this logic using
parameter
S
OP22.

The output is high when:
1 = HEALTH The Run signal is not present, or no
trip is active
2 = TRIPPED A trip is present
3 = RUNNING The motor is running
4 = AT ZERO The output frequency is below 1% of
MAX SPEED (

PID
PI is used to control the response of any closed loop system. It is used specifically in system
applications involving the control of drives to provide zero steady state error between Setpoint
and Feedback, together with good transient performance.
P
roportional Gain (
P
501)
This is used to adjust the basic response of the closed loop control system. The PI error is
multiplied by the Proportional Gain to produce an output.
I
ntegral (
P
502)
The Integral term is used to reduce steady state error between the setpoint and feedback values of
the PI. If the integral is set to zero, then there will always be a steady state error.
