Using SGD- N or SGDB- AN
(MECHATROLINK communication
support type)
Please use MECHATROLINK-II
communication reference servo
amplifier (SGDV- 1 type).
SGDV- 1 type servo amplifier
corresponds to MECHATROLINK-II
communication (4Mbps).
Changing software of the host controller
may become necessary when using the
SGDV- 1 type to replace
SGD- N type, SGDB- AN type,
because the corresponding
MECHATROLINK command is
different.
Using SGD- H (RS-422
communication support type) or
SGDB- AM (for multi-function
position control)
There is no option module with the
interface that can replace these. Please
consider the replacement with
MECHATROLINK-II communication
reference servo amplifier
(SGDV- 1 type).
Using SGDB- -P (duct
ventilation type)
Please inquire to the factory. Although
there is a model that corresponds to the
duct ventilation type but the capacity is
limited and the installation size is
different.
The following functions and performances were improved by replacing ∑ with ∑- V.
・ Added the small capacity medium inertia series (SGMJV type) to the motor lineup.
・ Increased the peak speed of the motor from 4500rpm to 6000 rpm. (SGMJV type and SGMAV type)
・ Improved the speed frequency response characteristic for performance.
SGDA / SGDB 250Hz ⇒ SGDV 1.6kHz (Load inertia＝Rotor inertia of motor）
・ Supports pulse train command input frequency of 4Mpps.
SIGN+PULSE and CW/CCW are 4Mpps. The A/B-phase 2-phase pulse train becomes 4Mpps at 1x2,
2Mpps at 2x2, and 1Mpps at 4x2.
However, it is 200kpps when connecting with open collector output.
・ RoHS compliant as standard product.
・ Safety standard (Safety Stop-0) embedded in standard products.
・ PC connection changed from RS-232C communication to USB.
