The
is a revolutionary hybrid stepping motor and driver package which eliminates missed steps. The
uses a built-in feedback device that constantly monitors the motor shaft position to detect and correct for loss of synchronism.
does not lose synchronism even when subjected to abrupt load fluctuation or acceleration. The newly developed rotor position detection sensor constantly monitors the motor movement. If synchronism is about to be lost, closed loop control is used, so there is no need to worry about loss of steps.
Like conventional stepping motors,
operates in synchronism with command pulses. This makes possible short stroke positioning in a short time.
Motor runs in open loop mode like a step motor.
Control switches to closed loop mode to prevent the loss of synchronism.
Gain tuning for servo motors is critical, troublesome and time-consuming. Since
operates like a stepping motor, there are no gain tuning requirements. Low rigidity applications, such as a belt and pulley system, are ideal for
.
Since
is a stepping motor, it has no hunting problem. Therefore, when it stops, its position is completely stable and does not fluctuate.
is ideal for applications in which vibration would be a problem.
The driver employs advanced technology that produces smoothness comparable to a microstepping driver. Its vibration level is incredibly low, even when operating in the low speed range. When frequent changes from low to high (or vice versa) speed operations are required, the use of the Resolution Select Function solves the problem.
The geared types enable driving of large inertial loads and positioning at higher accuracy, while the IP65 rated motor provides ingress protection against dust and water. The
offers a wide range of models meeting the needs of various applications.
RoHS (Restriction of Hazardous Substances) Directive:
Directive on restriction of the use of certain hazardous substances in electrical and electronic equipment (2002/95/EC).
The RoHS Directive prohibits the use of six chemical substances in electrical and electronic products sold in the EU member states. The six controlled substances are: lead, hexavalent chromium, cadmium, mercury and two specific brominated flame-retardants (PBB and PBDE).

Pulse Input
(Available in AC or DC Input)
Various motor controls can be performed using a pulse generator provided by the user.
Built-In Controller
(AC Input)
The built-in pulse generation function allows the motor to be driven via a directly connected programmable controller. Since no separate pulse generator is required, the drivers of this type save space, simplify wiring and also allow the number of axes to be increased with ease.
