3 PARAMETERS FOR POSITIONING CONTROL
3.7 Expansion Parameters
3.7
Expansion Parameters
The expansion parameters are data to execute the following operation by the parameters set in each axis.
• Monitor individually the positive and negative direction torque limit value.
• Change the acceleration/deceleration time when changing speed.
• When performing positioning control in the absolute data method on a degrees axis, specify the positioning direction.

*1 For direct setting using MT Developer2, use the decimal format instead of the exponential format.
*2 Refer to the indirect setting method by devices for parameters for the range of devices used for indirect setting. (
Setting Method by Devices for Parameters)
*3 This setting can be omitted.
*4 When 0 is set, a deceleration stop is executed according to the stop deceleration time set in the parameter block.
*5 Can be set when the unit setting of the fixed parameter is "degree".
*6 During position follow-up control, the values of devices that were indirectly set at the change of the positioning address are input again.
*7 For continuous trajectory control, operation is by the settings at the start, even if the settings were changed during operation.
