2. Precautions for Replacement
The following table shows the precautions for replacing the SS2 series with the G5 series.
Read the comparisons of both series shown in this manual and the User’s Manual of both series, before considering replacement.
No. Classification
Item
SS2 series
G5 series
Remarks
1.
Specifications
and
performance
Speed response
frequency
1 kHz or equivalent
2 kHz
Both the specifications
and performance are
improved in the G5
series.
2.
Encoder resolution
● Incremental encoder
Phases A and B: 2,500
pulses/rotation
(Multiple of 4: 10,000
pulses/rotation)
● Incremental encoder
Phases A and B: 262,144
pulses/rotation
(Multiple of 4: 1,048,576
pulses/rotation)
3.
Parameter Unit
Present
Absent
For the G5 series,
parameters are set from
CX-Drive (computer
tool).
4.
Servomotor
dimensions
Standard type
Example) 100 W motor:
□40×92
Example) 100 W motor:
□40×92
Same in dimensions.
5.
Flat type
Example) 100 W motor:
□60×60.5
Example) 100 W motor:
□40×92
The G5 series has no
flat Servomotors, so the
dimensions are
significantly different.
6.
Drip-proof structure
IP65
IP67
It is improved in the G5
series.
7.
Servo Drive
dimensions
Drive body
Example) 100 W drive:
120×35×105
Example) 100 W drive:
150×40×130
The drive dimensions of
the G5 series are
enlarged.
8.
Function
STO function
Absent
Present
All the functions are
covered because of
upward compatibility.
However, parameter
Nos. are different, so
