FSI Frequency
Setting Current
input
This is mainly used for setting the frequency (speed) input. A maximum
frequency setting is available at 20mA input. This setting is valid
when FSI
0-20mA, FSI 4-20mA, FSI 20-0mA or FSI 20-
4mA is selected as frequency
reference input in A106 or D204 or torque reference input in A108
. Also,
this input can be configured as PID Reference input (C603
) or PID
Feedback input (C604) or Math Reference Input2 (A702
) or Variable bias
(A706) for math operation.
IIN Current Input
This is mainly used for setting the frequency (speed) input. A maximum
frequency setting is available at 20mA input. This setting is valid when IIN
4-20mA is selected as frequency reference input in A106
. Also, this input
can be configured as PID Reference input (C603
) or PID Feedback input
(C604) or Math Reference Input2 (A702) or Variable bias (A706
) for math
operation.
VIN Voltage Input This is mainly used for setting the fre
quency (speed) input. A maximum
frequency setting is available at 10V input. This setting is valid when VIN
0-10V is selected as frequency reference input in A106
. Also, this input
can be configured as PID Reference input (C603
) or PID Feedback input
(C604) or Math Reference Input2 (A702) or Variable bias (A706
) for math
operation.
VO1 Vout-1 These are programmable analog voltage outputs 0-10V. In default
condition, output frequency signal is assigned to VO1 and output current
signal is assigned to VO2. Different seven internal signals can be
assigned to these outputs using C201 & C202.
VO2 Vout-2
IO1 Iout-1 These are programmable analog current outputs 4-20mA. In default
condition, motor power signal is assigned to IO1 and output voltage signal
is assigned to IO2. Different seven internal signals can be assigned to
these outputs using C203 & C204.
IO2 Iout-2
TX DATA+ These two signals are for the two-wire RS-485 serial link. The protocol
used is Modbus-RTU.
RX DATA-
PA A-Phase Pulses The A-phase positive pulse of encoder is applied at this terminal.
PAN The A-phase negative pulse of encoder is applied at this terminal.
PB B-Phase Pulses The B-phase positive pulse of encoder is applied at this terminal.
PBN The B-phase negative pulse of encoder is applied at this terminal.
+5V +5V source This is +5V source for the encoder. The encoder is required only in case
of close loop control mode. Refer chapter-10 for detail on encoder
specification.
FA Programmable
Fault Relay
Contacts
This is programmable relay and its function is assigned to “Fault”
condition in default. When a programmed condition occurs, the section
FA-FC is closed and the section FB-FC is open. Select from different
options using C113.
FC
FB
R1A Programmable
Relay 1 contacts
This is programmable relay and its function is assigned to “Run” condition
in default. When a programmed condition occurs, the section R1A-R1C is
closed and the section R1B-R1C is open. Select from different options
using C111.
R1C
R1B
R2A Programmable
Relay 2 contacts
This is programmable relay and its function is not assigned to any internal
signal in default. When any function is assigned using C112 and the
programmed condition occurs, the section R2A-R2C is closed and the
section R2B-R2C is open. Select from different options using C112.

The control circuit wiring is shown as under. The described precautions must be observed during
wiring. Changing the jumper position JP1 in PCA-2014A/PCA-2004A between “SINK” and “SOURCE”
position can change the sequence input between sink logic and source logic. Open cover designated
as “Control Unit” to access this jumper. The unit is shipped with sink logic.
