8 OUTPUT MODULE

(2) Roller diameter (L)/Number of pulses per roller revolution (NL)

(a) The roller diameter connected to servomotor and the number of pulses per

roller revolution are displayed.

Number of pulses per roller

revolution (N

)

Roller diameter (L)

(b) The roller cycle speed is calculated by the roller diameter and number of

pulses per roller revolution as the formula below.

1) Unit : [mm]

2) Unit : [inch]

The value calculated by calculations 1) and 2) is stored with an integer

value in the roller cycle speed storage register.

Output unit Roller cycle speed storage register

mm Calculated value 100

inch Calculated value 1000

(3) Permissible droop pulse value

(a) This device is used to set the permissible droop pulse value of deviation

counter.

(b) The deviation counter value is continually checked, and if it becomes larger

than the permissible droop pulse value, the error detection signal

(M2407+20n) turns on.

However, since the roller axis operation continues, execute the error

processing by user side.

(4) Speed control limit (VL)

(a) This device is used to set the maximum speed of roller axis.

(b) Set the speed limit value within the following range.

[Roller cycle speed] =
