Control
(continued)

Speed Control:

Speed Regulation - without feedback (Vector
Control Mode)

0.1% of base speed across 120:1 speed range
120:1 operating range
50 rad/sec bandwidth

Speed Regulation - with feedback (Vector Control
Mode)

0.001% of base speed across 120:1 speed range
1000:1 operating range
250 rad/sec bandwidth

Torque Regulation:

Torque regulation without Feedback;

±

5%, 600 rad/sec bandwidth

Torque regulation with Feedback;

±

2%, 2500 rad/sec bandwidth

Selectable Motor Control:

Sensorless Vector with full tuning. Standard V/Hz
with full custom capability and Vector Control with
Force Technology (with and without feedback).

Stop Modes

Multiple programmable stop modes including
Ramp, Coast, DC-Brake, Ramp-to-Hold, and
S-curve.

Accel/Decel

Two independently programmable accel and decel
times. Each time may be programmed from 0-3600
seconds in 0.1 second increments.

Encoder

Type:

Incremental, dual channel

Supply:

12V, 250 mA. 12V, 10 mA minimum inputs isolated
with differential transmitter, 250 kHz maximum.

Quadrature:

90°, ± 27 degrees at 25 °C

Duty Cycle:

50%, ± 10%

Requirements:

Encoders must be line driver type, quadrature
