Features; Specifications And Dimensions - Nakanishi E4000 CONTROLLER Operation Manual

5 . FEATURES

① Although it is a compact unit with a motor / spindle diameter of 40mm, the E4000 system is capable of
outputting high power with a maximum 1,200W, and high torque with a maximum 1.0N･m onto the motor shaft.
② The E4000 features a high speed type with a maximum speed of 40,000min
a maximum speed of 20,000min
③ Speed control and protection functions are incorporated in the high performance microprocessor.
④ A wide speed range, 1,000 - 40,000 min
-1
100min (rpm) make high precision machining possible.
⑤ Use of an external mechanism such as sequence control allows the E4000 series to be controlled from A CNC / PC
Control. In addition, power output can be monitored via external equipment.
⑥ The CONTROLLER can be placed horizontally or vertically. It can be installed at various places by using the
attached mounting bracket.
⑦ Each operation setting can be set with parameters (memory) that match each user's preferred operating
method.
⑧ Abnormality and malfunctioning status of the CONTROLLER can be checked by error code display by the
Error Detection (warning, error) of the system.
⑨ An overheat detection sensor is built into the motor, and problems due to abnormal overheating of the motor is
prevented before it damage occurs.
⑩ A straight type and right angle type electric and air connection is available to meet space limitations.
⑪ The motor / spindle housing is made from precision ground, hardened, stainless steel (SUS) with an outside
diameter of 40mm.
⑫ The motor cord is available from 2m to 8m in increments of 2m to meet machine electrical and NSK Control
distances.
⑬ The control panel is removable. It can be installed on the rear of the CONTROLLER, allowing for exibility of
operation.
⑭ The Control Panel can be installed at a distance of 4m from the CONTROLLER body by using an optional E4000
Control Panel Extension Cord.
⑮ In an Emergency Stop condition, the power to the motor can be securely disconnected via a relay by using
the E4000 Safety Relay Box. A safety system between the E4000 CONTROLLER and the machine can be
con gured by utilizing auxiliary contacts.
