00: 2-ms filter
01: 10-ms filter
10: 100-ms filter
11: 500-ms filter
S Bit 2: Torque limit auto judgement
0: Speed reference gain switching OFF
1: Speed reference gain switching ON
S Bit 3: Sensitivity switching selection when using servo mode * 2
0: Not judged
1: Judged
S Bit 4: Excessive speed deviation protection (AL-32) operation threshold
0: 1/2 or less of speed reference
1: 1/4 or less of speed reference
S Bit 5: Speed limiting level * 2
0: 105% of rated reference
1: 110% of rated reference
S Bit 6: Speed agree signal (AGR) output at zero speed

C1-40
Signal Selec-
tions 5
SEL5 * 4
Control mode signal selections
S Bit 1 and 0: Operation delay time for excessive speed deviation protec-
tion (AL-32)
00: 0 s 01: 0.3 s
10: 0.4 s 11: 0.5 s
S Bit 2: Torque detection signal (TDET) output
0: Standard output
1: ON for acceleration/deceleration
S Bit 3: NC orientation
0: Disabled.
1: Enabled. Even if orientation signal (ORT) is input, the
Inverter will not perform orientation. The rotating
direction of motor is determined according to the polar-
ity of speed reference.
S Bit 4: Load meter output standard selection * 2
0: Continuous rated output
1: 30 min. rated output
S Bit 5: Servo mode speed reference gain selection (Enabled when bit 3 of
C1-38 is ON.) * 2
0: Analog speed reference, 10 V/5,000 rotations/min.
1: Set the read gain of the analog speed reference using
C1-49 or C1-50.
S Bit 7: Load fault detection selection (AL-33)
0: Disabled
1: Enabled
