Servo Amplier - Installation

PROGRAM MODES
Operation With A Pulse Source
Complete a motor, power, and I/O wiring to the
terminal block. When wiring for pulse and direc-
tion, Channel A is the pulse input and Channel B
is the direction input. Apply a soure of 115 VAC to
the IMJ. Connect the S2K serial port to a personal
computer or other serial terminal device. Refer
to the S2K Hardware Manual for serial port wir-
ing and Serial Port. (Refer to Page 4) Congure
your serial terminal for 9600 baud, 7 data bits, 1
stop bit, and odd parity. Verify that the serial port
is working by typing 1FC?<Enter> and observe
the response. Then proceed with the following:
• Type STF<CR>, the controller will respond
“*”.
• Type KLALL<CR>, the controller will respond
“*”.
• Type VI1=0<CR>, the controller will respond
“*”.
• Type VF10 through VF18 to the appropriate
values. (The factory supplied default values
should work for most applications. Contact Rans-
burg if there are any questions about what values
should be entered.) (Refer to Figure 3)
• Select desired PLA to correspond to the re-
quired gear ratio.
• Type SAVE, the controller will respond, “Sav-
ing user memory... User memory saved.”
• Once all parameters have been set, type EXP1,
the controller will respond, “Variables have been
saved to ash memory.”
This indicates that all variables, registers, and
programs have been saved. To start the motor,
cycle the “Enable” input from false to true.
• Toggle the “Enable” signal.
The S2K will rotate the motor in synchronism with
the input pulse source. In this mode, the motor
displacement is proportional to the number of
pulses received, and motor speed is proportional
to the frequency of the pulse train.
The following table represents typical Pulse
Source setup parameters. However, depending
on the vintage of the system that this amplier
is being retrotted to, the following parameters
could be different:
• VI1 should be setup to a value of 0, (VI1 tells
the amplifer how to function, in either pulse mode
or analog mode).
• VI4 should be set to 0, but a verication of
direction may be required and a setting of 1 may
be required in some applications (VI4 tells the
amplier what direction the motor is to be running).
• VF18 should be set for 150, but an older vin-
age system may require a setup of 120 (VF18
tells the amplier what the maximum shaft output
speed is to be).
