• MD3214 (Pn20E) ELECTRIC_GEAR_NUMERATOR_LW (For each axis)
Meaning: Electronic gear ratio numerator (Lower word)
Setting value: [Pulse]
• MD3215 (Pn20F) ELECTRIC_GEAR_NUMERATOR_HW (For each axis)
Meaning: Electronic gear ratio numerator (Upper word)
Setting value: [Pulse]
Note: Electric gear functions at CNC side are to be used. Assign the factory
setting value (1, 0) to MD3214 and MD3215.
• MD3216 (Pn210) ELECTRIC_GEAR_DENOMIN_LW (For each axis)
Meaning: Electronic gear ratio denominator (Lower word)
Setting value: [Pulse]
• MD3217 (Pn211) ELECTRIC_GEAR_DENOMIN_HW (For each axis)
Meaning: Electronic gear ratio denominator (Upper word)
Setting value: [Pulse]
Note: Electric gear functions at CNC side are to be used. Assign factory set-
ting value (1, 0) to MD3216 and MD3217.
You do not need to set the number of motor encoder pulses because it is read from an encoder directly.
You can check the number of encoder pulses with the following drive parameters.
• MD1005 ENC_RESOL_MOTOR (For each axis)
Meaning: Motor encoder resolution
• MD1042 RESOLUTION_G1_XIST1 (For each axis)
Meaning: Motor encoder resolution magnification 1
The number of motor encoder pulses = MD1005
