Description of RSi S4 Control Terminals
Terminal Description
Vmet
Analog output 1, which is a dedicated voltage output.
The default signal range is from 0 to 10 Vdc (5 mA maximum). It is proportional to the variable congured by parameter
I/O 32 - Vmet Cong. It may be calibrated while the drive is running via parameter I/O 34 - Vmet Span.
Imet
Analog output 2, which is a dedicated current output.
The default signal ranges from 0 to 20 mAdc (50 to 500 Ohms). It is proportional to the variable congured by parameter
I/O 33 - Imet Cong. It may be calibrated while the drive is running via parameters I/O 36 - Imet Offset and I/O 35 - Imet Span.
Vin1
Analog Input 1, which is used to provide speed references.
The default input signal is 0 to 10 Vdc (the type of input signal is selected with parameter I/O 19 - Vin1 Cong. Parameters
I/O 20 - Vin1 Span and I/O 21 - Vin1 Offset may be used to offset the starting value of the range and the size of the range,
respectively; see parameter DRV 05 also.
If a 0 to 20 mAdc input signal is congured, the burden is 250 Ohms. If a 0 to 10 Vdc input signal is congured, the input
impedance is 475kOhms.
A potentiometer in the range of 1 to 10 kOhms is recommended for this input.
+10
This terminal is a +10 Vdc source for customer-supplied potentiometers. The maximum load on this supply cannot exceed
10 mAdc.
Cin+ / Cin-
Current Input.
The default input signal is 4-20 mA, although this range may be adjusted by using parameters I/O 25 - Cin Offset and
I/O 24 - Cin Span (to reduce or enlarge the range — for example, setting Cin Span to 50% results in a range of 4-12 mA).
The burden for this terminal is 50 Ohms.
Vin2
Voltage Input 2, which is used to provide speed references.
The default input signal is 0 to 10 Vdc. The type of input signal is selected with parameter I/O 27 - Vin2 Cong. Parameters
I/O 28 - Vin2 Span and I/O 29 - Vin2 Offset may be used to offset the starting value of the range and the size of the range,
respectively. If a 0 to 20 mAdc input signal is congured, the burden is 250 Ohm. If a 0 to 10 Vdc input signal is congured, the
input impedance is 475 kOhms.
A potentiometer in the range of 1 to 10 kOhms is recommended for this input.
Acom
Common for the Analog Inputs and Outputs. Note that while there are two Acom (common) terminals, they both
connect to the same electrical point.
+24
A source for positive nominal 24 Vdc voltage. This supply has a source capacity of 150 mA.
FWD
Forward Direction Selection terminal. This may be connected for two-wire maintained or three-wire momentary operation.
REV
Reverse Direction Selection Terminal. This may be connected for two-wire maintained or three-wire momentary operation.
R/J
3-wire latch terminal. When this terminal is connected to +24 or common (depending upon Active Logic setting),
momentarily connecting either FWD or REV to +24 results in a latched run mode (3-wire operation).
MOL
Motor Overload input terminal. This requires a N/O or NC contact for operation, referenced to +24 or COM, depending
on Active Logic setting.
EN
Enable terminal. A jumper is placed between this terminal and the +24 terminal at the factory. You may replace this
with a contact, if desired. The circuit from EN to +24 must be closed for the drive to operate.
Note that unlike all other terminals, this terminal cannot be congured for “pull-down logic.” That
is, a high input to this terminal is always regarded as true, and must be present for the drive to
operate.
Dcom
Digital Common for use with digital inputs and +24 internal power.
DI1-DI5
Digital inputs. The selectable digital inputs are programmed via I/O 02 to I/O 06.
NC1
NO1
RC1
The rst auxiliary relay. The function of the relay is set by parameter I/O 10 - R1 Cong. The default setting is for
the relay to activate when the motor is faulted. Terminal NO1 is the normally-open contact, which closes when the
relay is activated. Terminal NC1 is the normally-closed contact, which opens when the relay is activated. Terminal
RC1 is the common terminal.
NC2
NO2
RC2
The second auxiliary relay. The function of the relay is set by parameter I/O 11 - R2 Cong. The default setting is
for the relay to activate when the drive is running. Terminal NO2 is the normally-open contact, which closes when the relay is
activated. Terminal NC2 is the normally-closed contact, which opens when the relay is activated. RC2 is the common terminal.
DO1
DO2
Digital Outputs 1 and 2. The function of the outputs is set by parameter I/O 08 - D1 Cong and I/O 09 - D2 Cong. The default
setting for DO1 is Drive Ready; for DO2 it is At Speed.
DOP
Open collector transistor output that supplies a pulse train proportional to speed. The frequency of the output is set
by parameter I/O 42 to either 6x or 48x the running frequency. The output has a maximum rating of 28 Vdc and
requires a pull-up resistor (4.7 kOhms) if using the drive’s internal supply.
Note that if you are using a high-impedance meter to this terminal, the pull-up resistor value may need to change. Please consult
the factory for more information
