7.1 Setting User Constants

■ Cn-0002 Bit 0: Motor Rotation Direction

• Sets the motor rotation direction.

• Determines whenever Cn-0002 bit 0 or 2CN-7 is the reverse rotation with a reverse rotation

setting.

• The forward direction is clockwise when Cn-0002 bit 0 is set to 1. (Reverse Rotation Mode).

■ Cn-0002 Bit 1: Pulse Count Check for Absolute Encoder

• Cn-0002 bit 1 is valid only when an absolute encoder is used.

• Cn-0002 bit 1 is used to check whether the number of PG pulses (phase A and B) between

origin pulses (phase C) match the number of pulses per revolution when an absolute encoder

is used.

• This check is disabled when Cn-0002 bit 1 is set to 1.

■ Cn-0002 Bit 6: Software Limit Check by A Reference

• Cn-0002 bit 6 is used to determine whether the software limit check is enabled when a posi-

tion reference such as POSING or INTERPOLATE or other is input.

• The software limit check is enabled when Cn-0002 bit 6 is set to 1.

■ Cn-0013 Bit 10: MECHATROLINK Communication Check Mask

• Cn-0013 bit 10 is used to cancel the communication check for debugging.

• Normally, set Cn-0013 bit 10 to communication check enabled.

• The communication check can be canceled by setting Cn-0013 bit 10 to 1.

■ Cn-0013 Bit 11: WDT Check Mask

• Cn-0013 bit 11 is used to cancel the WDT check for debugging.

• Normally, set Cn-0013 bit 11 to WDT check enabled

• The WDT check can be canceled by setting Cn-0013 bit 11 to 1.

■ Cn-0014 Bit 1: Zero Point Return Direction

• Set this bit to 0 when zero point return direction is the forward direction (+) .

• Set this bit to 1 when zero point return direction is the reverse direction (—).

■ Cn-0014 Bit 2: P-SOT Mask

• Cn-0014 bit 2 is used to set whether the forward software limit check is enabled.

• The forward software limit check is disabled when Cn-0014 bit 2 is set to 1.

■ Cn-0014 Bit 3: N-SOT Mask

• Cn-0014 bit 3 is used to set whether the negative software limit check is enabled.

• The negative software limit check is disabled when Cn-0014 bit 3 is set to 1.
