15. SERVO AMPLIFIER CONNECTION
15.6 Device Range that Can Be Set
(1) When selecting [All] in the Network setting
The network No. 0 and Station No. FF are
displayed on Device List and when printing.
(Device List screen)
(2) Monitoring servo amplifier
Carefully read the manual of servo amplifier to be
connected and fully understand the operating
procedures before monitoring.
Before operation, check the parameter settings.
Improper settings may cause some machines to
perform unexpected operation.
The parameter settings must not be changed
excessively. Operation will be insatiable.
(3) Parameters with * in front of it's abbreviated name
For the parameter with * in front of it's abbreviated
name, powering off the servo amplifier after setting
then on makes the parameter valid.
(4) Data length for setting virtual devices for servo
amplifier
Set the following data length for setting devices.
• PRM, ST, AL, PA, PB, PC, PD, POS, SPD, ACT,
DCT, DWL, AUX
: 16bits or 32bits (depends on the data of servo
amplifier)
• DI, DO, TMI, TMO, TMD: 32bits
If the above data length was not set, data would
not be set to the servo amplifier correctly or the
GOT can not monitor normally.
(a) Monitoring
• When the 16-bit data is handled as 32-bit
data, the upper 16bits are displayed as 0.
• When the 32-bit data is handled as 16-bit
data, the lower 16bits only are displayed as
0.
(b) Writing
The GOT writes within the range of data
length set. Note that the servo amplifier
responds correctly while the written data is
invalid in the servo amplifier side when the
written data is outside the range of values
which can be set by the servo amplifier.
(5) Memory area for writing parameters
Parameters are written to RAM or E
2
PROM of
servo amplifier.
(a) When written to RAM
Remember that written parameters are
cleared when power supply to the servo
amplifier is turned off.
(b) When written to E
2
PROM
Written parameters are not cleared even
when power supply to the servo amplifier is
turned off.However, there are limits in the
number of writing to E
2
PROM.
If the data is frequently updated (more than
once in an hour), write the parameters to the
RAM.
For details, refer to the manual of the servo
amplifier used.
