The constant settings that indirectly change control performance are listed below.
Table 4.4 Constants that Indirectly Change Control Performance and their Functions
Name (Constant No.) Functions
Acceleration/deceleration time (C1-01 to -11) Adjusts the torque during acceleration and deceleration.
S-curve characteristics (C2-01 to -04) Used to prevent shock at completion of acceleration/deceleration.
Jump frequency (d3-01 to -04) Used to avoid machine resonance points during operation.
Analog input filter time constant (H3-16) Used to prevent fluctuation of analog input signals caused by noise.
Stall prevention (L3-01 to -03)
Used to prevent motor stall or overvoltage (OV) for heavy-load operation
or rapid acceleration.
Factory setting: Disabled
Torque limit (L7-01 to -04)
Sets the maximum torque for vector control. When increasing the setting,
use an Inverter with higher capacity than the motor. Excessively decreas-
ing the setting under heavy load will cause motor stall.
