5.4 Analog I/O details
5.4.1 Analog reference input
IN+, IN- (TB506-23, 24 or TB502-2,3)
Analog differential input. This input will accept +/-10V single-ended voltage on IN+ or IN- input or
+/-5V differential voltage between IN+ and IN-. Both connections must be referenced to Analog
Common (TB506-25 or TB502-5) of the drive. This input is used to control speed or torque of the
motor in velocity or torque mode (SS500/600 only).The total reference voltage as seen by the drive is
the voltage difference between IN+ and IN-. If used in single-ended mode one of the inputs must be
connected to voltage source while the other one must be connected to Analog Common. If used in
differential mode, the voltage source is connected across IN+ and IN- inputs and driving circuit
common (if any) needs to be connected to drive Analog Common terminal.
Reference as seen by drive:
Vref = (VIN+) - (VIN-)
Note
In SSi1000 drives, Vref is available by reading System Variable “AIN”.
5.4.2 Analog output
Analog out. (TB502-10)
Analog output is single ended –10/+10V span signal which can represent different quantities of the
drive (SS500/600 only). For SS500/600 drives MotionView SetUp program can be used to select
signal source for the analog output as well as its scaling. SSi1000 indexing drives can set analog
output directly from User program (Sysytem Variable “AOUT”) or via Host Interface command. Load
capability of that output is 10mA.
5.5 Communication interfaces (SS500/600 drives)
Drives are equipped with RS232 communication interface. Communication speed is fixed at 38,400
baud.
5.6 Communication interfaces (SSi1000 drives)
In addition to standard RS232 interface SSi indexing drives have RS485 and Ethernet communication
interfaces. Communication speed for RS232/485 can be 115200 or 38400 baud and DIP-SWITCH
DS501 #6 selectable.
5.6.1 RS232 interface
This interface is available on SSi drives for communication with Host computer. The SSi RS232 is
addressable, with the address set by DIP-SWITCH DS501. See “RS485 interface” paragraph below to
see how address should be set. The SSi RS232 has a unique re-transmitting feature. If you send
commands using RS232 interface to the drive with a different address, the drive will retransmit this
command to the RS485 network so the other drive might pick it up. This allows the possibility of
connecting a network of SSi drives to a Host computer via RS232 on one of the drives in the network.
There is no special adjustments or setups needed to start using this feature.
