D
Forward Torque Control: Cn-08
Reverse Torque Control: Cn-09
The Servomotor output torque control value for forward rotation is set in Cn-08, and the value for re-
verse rotation is set in Cn-09. The setting range is 0 to the maximum torque, and the factory setting is for
the maximum torque.
D
Encoder Divider Rate: Cn-0A
The number of pulses detected (A- and B-pulses) per encoder revolution is converted to the number of
pulses set for this parameter and output from the Servo Driver. The setting range is 16 to 2,048 pulses/
revolution, and the factory setting is for 1,000 (pulses/revolution).
D
Rotational Speed for Servomotor Rotation Detection: Cn-0b
This sets the rotational speed for detecting whether or not the Servomotor is rotating. The setting range
is 1 to 4,500 r/min. When motor rotation detection has been set for the sequence output signal switch
(Cn-01 bit 4 = 0), the Servomotor rotation detection output (TGON: CN1-9) is turned ON if the Servomo-
tor rotational speed meets or exceeds this set value. The factory setting is for 20 (r/min).
D
P Control Switching (Torque Command): Cn-0C
P Control Switching (Speed Command): Cn-0d
P Control Switching (Acceleration Command): Cn-0E
P Control Switching (Deviation Pulse): Cn-0F
These set the various points for switching the speed controller from PI control to P control in order to
moderate excessive characteristics when an operation such as acceleration or deceleration is
executed accompanied by output saturation of the controller. These selections are made by setting the
setup parameter Cn-01 bit nos. b, d and C.
D
Jog Speed: Cn-10
This sets the speed for manual operation. The setting range is 0 to 4,500 r/min. During manual opera-
tion, operating commands are given from the Parameter Unit. The factory setting is for 500 (r/min).
D
Number of Encoder Pulses: Cn-11
This sets the number of pulses per revolution of a connected encoder. Do not change this parameter’s
setting; the Servomotor might not operate correctly if it is changed. The factory setting is for 2,048
(pulses/revolution).
D
Brake Timing 1: Cn-12
Brake Command Speed: Cn-15
Brake Timing 2: Cn-16
These parameters determine the output timing of the brake interlock signal (BKIR), which controls the
electromagnetic brake.
Brake timing 1 sets the delay time from the time of brake interlock goes OFF until the servo turns off. The
setting range is 0 to 50 (
×
10 ms), and the factory setting is for 0 (
×
10 ms).
The brake command speed is the speed (r/m) used to turn OFF the brake interlock. The setting range is
0 to 4,500 (r/m) and the factory setting is for 100 (r/m).
Brake timing 2 sets the wait time from when the servo goes OFF until the brake interlock goes OFF. The
setting range is 10 to 100 (
×
10 ms), and the factory setting is for 50 (
×
10 ms).
