User’s Manual of RDC6442G(U)-DFM-RD Control System

motor lose steps, jar and even squeak; if too small, it will cause the reduction of

acceleration so as to reduce the running speed of the whole figure. For the axles with

larger inertia, such as Y axle corresponding to the beam, its typical setting range is

800~3000mm/s2; for the axles with smaller inertia, such as X axle corresponding to the

car, its typical setting range is 8000~20000mm/s2.

 Scram Acceleration: if this axle enables the hard-spacing protection, when this

axle moves to the spacing position, it will scram operation at the scram acceleration.

This value can be 2~3 times of the maximum acceleration for this axle.

Key parameters

 Key Move Takeoff Speed: it means the starting speed to move this axle by

way of the keys on the keyboard, which can’t be higher than the takeoff speed.

 Key Move Acceleration: it means the acceleration to move this axle by way of

the keys on the keyboard, which can’t be higher than the maximum acceleration of this

axle.

 Key Polarity: it is used to control the movement direction of the axle that is

moved through manual operation of the keys. After the direction polarity is correctly set,

if you press the directional keys on the operating panel, this axle will move to the

opposite direction. In such a case the polarity of keys should be modified.

（2）Laser parameters

 Laser Configuration: single laser and double lasers are available for option

and set in accordance with the laser-tube quantity provided by the manufacturer.

 Laser Type: glass tube, RF laser (not need pre-ignition pulse) and RF laser

(needing pre-ignition pulse) available for option.

 Laser Attenuation Quotiety

 Laser Enable: When double lasers are used, then each laser can be

respectively enabled or disabled.

 Minimum Power

 Maximum Power

 Laser PWM Frequency

 Pre-generation Frequency

 Pre-generation pulse scale: When the laser is RF-laser and it’s need to

pre-generate PWM, then set the Pre-generation Frequency and the Pre-generation

pulse scale.

 Water Protector Enabled: When the water protector is enabled, the mainboard will

detect the input port of water protector. If this port is of low level, it will be deemed normal; if this

port is of high level, the mainboard will forcibly close the laser to suspend the work in progress

and the system will warn. If the water protector is not enabled, the mainboard will not detect the

input port of water protector and so the water protector can be unconnected.

Laser PWM Frequency is used to set the pulse frequency of control signal used by this

laser, in general, glass tube is about 20KHZ, RF laser is about 5KHZ; the maximum/minimum
