MDS-E/EH Series Instruction Manual
5 Servo Adjustment
POINT
1. SV048 and SV055 are set for each axis, but when using MDS-E/EH-V2/V3 (2-axis or 3-axis drive unit), the axes are
controlled with the larger setting value.
2. If an alarm, for which dynamic brake stopping is designated, occurs with the axis for which vertical axis drop prevention
control is active, the function will not activate.
3. A drop amount of several µm to several 10µm may be generated due to brake play.
CAUTION
1. Do not set the vertical axis drop prevention time longer than required. The servo control and brakes could collide,
resulting in an overload alarm or drive unit damage. There is no problem if the overlapping time is within 100ms.
2. Vertical axis drop prevention control (including deceleration control) longer than 100ms will not be guaranteed during a
power failure. The operation will change to dynamic brakes.
3. If only SV048 and SV055 are set, and SV056 is set to 0, the deceleration stop will be a stepped stop and could result in
collision with the machine.
