3-1-3 Detailed information on I/O signals

(1) Position control mode
1) Torque limit
a. Torque limit and generated torque
By setting parameter No. 28 (internal torque limit 1), torque is always limited to the maxi-
mum value during operation. A relationship between limit value and servo motor-gener-
ated torque is shown in Fig. 3-1.
A relationship between the applied voltage of the analog torque limit (TLA) and the torque
limit value of the servo motor is shown in Fig. 3-2. Generated torque limit values will vary
about 5% relative to the voltage depending on products.
At the voltage of less than 0.05V, generated torque may vary as it may not be limited
sufficiently. Therefore, use this function at the
voltage of 0.05V or more.
