Nexen RSD200 964533 - Manual (Page 4)

FORM NO. L-21195-A-0904 4
16: Torque Actuator defines the type of device creating
the web tension. It has a value of 1 for a pneumatic
brake or clutch or 2 for a motor drive system or
magnetic particle brake or clutch. Read and write
integer values only. The default value is 1.
17: Application defines whether the RSD200 controls
tension during unwinding or winding. It has a value
of 1 for unwinding or 2 for winding applications.
Read and write integer values only. The default
value is 1.
18: Minimum Output is the minimum output level limit
that the RSD200 is allowed to reach. It has a range
of 1 to 100 % and is typically set to 1 % and must
be set to a value lower than Maximum Output. Read
and write integer values only. The default value is 1.
19: Maximum Output is the maximum output level limit
that the RSD200 is allowed to reach. It has a range
of 1 to 100 % and is typically set to 100 % and
must be set to a value greater than Minimum
Output. Read and write integer values only. The
default value is 100.
20: Stopped Output is used to limit how high the
output can go while the web is stopped and the
RSD200 is not in Run mode. This value supersedes
the Maximum Output value during stopped condi-
tions. It is used in applications when the machine is
stopped and a limited amount of drag tension is
desired on the web. It is has a range of 1 to 100 %
and is typically set to the same value as Maximum
Output. Read and write integer values only. The
default value is 100.
CALIBRATION REGISTERS
Calibration registers are read or written to during the installation and start up of a RSD200 system and seldom change
afterwards. Registers 21 and 22 tell the RSD200 to determine the position of the dancer arm when the arm is predefined
positions for the purpose of calibrating the dancer position sensor. Web Tension registers provide the RSD200P with
information to calibrate the dancer arm loading cylinder pressure to the total web tension. It is only used with RSD200P
models.
ADDRESS
21: Read Maximum Storage Position causes the
RSD200 to measure the position of the dancer arm
in its maximum web storage position when a 1 is
written to this register. This is a write only register
and reading from it will only return a zero.
22: Read Minimum Storage Position causes the
RSD200 to measure the position of the dancer arm
in its minimum web storage position when a 1 is
written to this register. This is a write only register
and reading from it will only return a zero.
23: Minimum Arm Pressure is the dancer arm loading
cylinder air pressure that corresponds to the
minimum operating total web tension. It has a range
of 1.0 to 100.0 psi. This value is multiplied by 10
before sending or receiving in order to convert it to
an integer. Default value is 1.0.
24: Minimum Web Tension is the minimum operating
total web tension that corresponds to Minimum Arm
Pressure. It has a range of 1.0 to 500.0 lbs. This
value is multiplied by 10 before sending or receiving
in order to convert it to an integer. Default value is
1.0.
25: Maximum Arm Pressure is the dancer arm loading
cylinder air pressure that corresponds to the
maximum operating total web tension. It has a range
of 1.0 to 100.0 psi. This value is multiplied by 10
before sending or receiving in order to convert it to
an integer. Default value is 2.0.
26: Maximum Web Tension is the maximum operating
total web tension that corresponds to Maximum Arm
Pressure. It has a range of 1.0 to 500.0 lbs. This
value is multiplied by 10 before sending or receiving
in order to convert it to an integer. Default value is
2.0.
