POINT
When the cam reference position setting command (M3214+20n) is OFF, a
position of cam axis is restored in the range of 0 to 359.99999[degree]. If the cam
stroke amount is lager than 360.00000[degree], the current value within 1 cam
shaft revolution different from the previous virtual mode might be restored.
(Example) When cam position is restored by switching to virtual mode in the
following conditions, the current value within 1 cam shaft revolution
corresponding to "current feed value: 80[degree]" is restored.
• Stroke amount : 720[degree]
• Lower stroke limit value : 0[degree]
• Current value
: Lower stroke limit value + 440[degree]
(Current feed value: 80[degree])
(6) Torque limit value setting device (1 word)
(a) This device is used to set the torque limit value for cam shaft.
When the device is set, the torque control is executed with the preset device
value.
In the virtual mode, the torque limit setting is always valid.
If the device is not set, the torque limit is set at 300[%].
(b) The following devices can be set as the torque limit value setting device.
Name Setting range
Data register
D0 to D8191
(Note-1)
Link register W0 to W1FFF
Motion register #0 to #7999
Multiple CPU area device U \G10000 to U \G(10000+p-1)
(Note-2)
(Note-1): D800 to D1559 are dedicated devices of virtual servomotor axis,
synchronous encoder axis and output module "Cam" in the virtual mode.
Unused areas of virtual servomotor axis and cam axis can be used as a
user device.
(Note-2): "p" indicates the user setting area points of the Multiple CPU high speed
transmission area for each CPU.
(c) The setting range for torque limit value is 1 to 1000[%].
(7) Comment
(a) This device is used to create a comment such as purpose of cam shaft.
Made comment can be displayed at monitoring using MT Developer2.
(b) Comments up to 32 characters long can be created.
