Configuring Terminal 10 (Digital Input/Output)
Terminal 10 can be operated as digital input DIN 4 or digital output DOUT2. It is configured
via the keypad. The default for terminal 10 is to operate as a digital input, and the input logic is
non-inverted.
Configure for use as a Digital Input (default)
For example, 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.
Parameter
Setting
DOUT2 SOURCE
0
DOUT2 INVERT
0
DIN4 INVERT
Default is 0, setting to 1 inverts the input logic
Configure for use as a Digital Output
For example, to use terminal 10 as an output, select
S
OP21 to be 1, 2, 3, 4 , 5 or 6. For instance,
you could set parameter
S
OP21 to 3 to have the output go high (24V) whenever the motor is
running, operating an external relay or lamp. You can invert this logic using parameter
S
OP22.
Parameter
Setting
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 (
P
2)
5 = AT SPEED
The output frequency is at or near
Setpoint and within ±1% of MAX
SPEED, set by (P2). For example:
if MAX SPEED = 50Hz and Setpoint
= 30Hz, then 1% of MAX SPEED =
0.5Hz. So AT LOAD is True
between 30 ±0.5Hz.
DOUT2 SOURCE
Always set
S
IP04 to 0 if using Applications 1 and 5 –
refer to Chapter 12.
DOUT2 INVERT
Default is 0, setting to 1 inverts the output logic
PID - Tuning Your Drive
Parameters
P
501 to
P
509: PID 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.
