Yaskawa Sigma-II Large Capacity - Manual (Page 4)

Using MP940 of one axis machine
controller
MP940 equivalent products are not
available in the option module. Please
consider t replacing with a combination
of MP2400/MP2300S of multi-axes
machine controller, and
MECHATROLINK-II communication
reference servo amplifier
(SGDV- 1 type) may be
necessary.
The following functions and performances were improved by replacing ∑-II with ∑- V.
・Added the small capacity medium inertia series (SGMJV type) to the motor lineup.
・Increased the max speed of the motor from 5000rpm to 6000rpm. (SGMJV type and SGMAV type)
・Improved the speed frequency response characteristic for performance.
SGDM / SGDH 400Hz ⇒ 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.
・PC connection changes from RS-232C communication to USB.
