6.PARAMETER SETTING
6.1 Mechanical equipment system
This section explains the parameter setting according to the mechanical equipment system driven by motor.
6.1.1 Change of rotational direction
This parameter makes the motor rotational direction match the machine moving direction.
System parameter 80
Para. Name Setting range Initial value Change
80 Rotational direction changeover 0 : Positive direction / forward
1 : Positive direction / reverse 0 Power
A selected rotational direction affects any of speed control, position control and torque control.
Speed control: The positive direction means the rotational direction when a positive (+) voltage is applied to speed command voltage
terminal [NREF] (multistep speed), and forward command [FWD] is given. The motor output shaft rotates forward.
Position control: The positive direction means the rotational direction when a forward pulse or command code at H level, or a pulse train of
two 90° phase-different (B-phase advance) signal is applied. The motor output shaft rotates forward.
Torque control: The positive direction means the rotational direction when a positive (+) voltage is applied to the torque command voltage
terminal [TREF], and forward command [FWD] is given. The motor output shaft rotates forward.

- Forward rotation, reverse rotation
Forward rotation is counter-clockwise (CCW) rotation when viewed from a point facing the drive-end of motor. Clockwise rotation is reverse
rotation.
When forward command [FWD] is given to amplifier and speed command (reference) voltage is positive (+), the motor rotates forward. To
rotate its direction in reverse, change the system para. 80 setting.
- Speed command [NREF], Torque command [TREF]
Each terminal accepts dual polarity voltage input of -10 to 0 to +10V.
When a negative (-) voltage is input and reverse command [REV] is given, the motor rotates forward.
- Resolution of speed command [NREF]
The resolution is 14 bit at full scale. When a speed reference voltage of 5000[r/min] /10V is given, (-5000 to +5000) [r/min] / 2
14
= 0.6 [r/min]
is obtained.
- Resolution of torque command [TREF]
The resolution is 10 bit at full scale. When a torque reference voltage of 300% /10V is given, (-300 to +300) % / 2
10
= 0.6 % (100% at rated
torque) is obtained.
