■Servo parameter
• Control of servo parameters
Parameters of AlphaStep/5-phase are not controlled by the Simple Motion module. Therefore, even though the parameter of
AlphaStep/5-phase is changed during the communication between the Simple Motion module and AlphaStep/5-phase, the
change is not applied to the buffer memory.
• Servo parameter change request
Change request of servo parameter ("[Cd.130] Servo parameter write request" to "[Cd.132] Change data") can be executed.
The servo parameter of AlphaStep/5-phase is controlled in a unit of 2 words. However, "1" (1 word write request) and "2" (2
words write request) can be set in "[Cd.130] Servo parameter write request".
Refer to the AlphaStep/5-phase manual for the specification method of parameters to change.
When the power of AlphaStep/5-phase is turned off, the parameter changed by the servo parameter change request becomes
invalid, and the value written by AlphaStep/5-phase data editing software becomes valid.
■Optional data monitor
The following shows data types that can be set.
Data type
Encoder multiple revolution counter
Position feedback (Used point: 2 words)
Encoder position within one revolution (Used point: 2 words)
External encoder counter value (Used point: 2 words)
■Gain switching command, PI-PID switching request, and Semi/Fully closed loop switching
request
Gain switching command, PI-PID switching request, and Semi/Fully closed loop switching request are not available.
■Driver communication
The driver communication is not supported.
If the driver communication is set in a servo parameter, the setting is ignored.
■Torque limit
The torque limit set by the Simple Motion module is ignored. Set the torque limit value with the parameter on the AlphaStep/5-
phase side.
■Axis monitor data
• "[Md.104] Motor current value" is always "0". When the optional data monitor is not used, "[Md.109] Regenerative load
ratio/Optional data monitor output 1", "[Md.110] Effective load ratio/Optional data monitor output 2", and "[Md.111] Peak
load ratio/Optional data monitor output 3" are "0".
• "Zero passage" ([Md.119] Servo status 2: b0) is always OFF.
• "Zero speed" ([Md.119] Servo status 2: b3) and "Speed limit" ([Md.119] Servo status 2: b4) are always OFF.
• "[Md.113] Semi/Fully closed loop status" is always "0".
• "[Md.107] Parameter error No." is always "0".
• "In-position" ([Md.108] Servo status 1: b12) is OFF during the axis operation. It is turned ON when the axis operation is
completed.
■Amplifier-less operation
The amplifier-less operation cannot be used to the AlphaStep/5-phase axis. If the amplifier-less operation is used, the
AlphaStep/5-phase set axis is not connected.
■In-position range
When the position of the cam axis is restored in synchronous control, a check is performed by the servo parameter "In-
position range" (PA10). However, because the servo parameter settings are not performed in AlphaStep/5-phase, the "In-
position range" is checked as 100 [pulse].
