performing acceleration and deceleration movements. Please refer to full version manual V1.1 “6.4.3 Torque
instruction limit”.
Forward speed limit
in torque mode
Protection and
restriction
Used to set forward speed limit value in torque control mode. Please refer to full version manual V1.1 “6.4.4
Speed limit in torque mode”.
Reverse speed limit
in torque mode
Protection and
restriction
Used to set reverse speed limit value in torque control mode. Please refer to full version manual V1.1 “6.4.4
Speed limit in torque mode”.
Protection and
restriction
When torque is limited by the setting value of P01-15 or P01-16, and exceeds the setting time, drive would
report fault “torque saturation abnormal”.
✎Note: When this function code is set to 0, saturation timeout fault detection would not be performed, and
this fault is ignored.
Zero-speed clamp
function selection
Please refer to full version manual V1.1 “6.3.4 Zero-speed clamp function”.
Force speed to 0, and keep position locked when the actual speed is less than P01-22
When the actual speed is less than P01-22, force speed to 0, and keep position locked
Invalid. Ignore zero-speed clamp input
Zero speed clamp
speed threshold
Used to set the speed threshold of zero-speed clamp function Please refer to full version manual V1.1 “6.3.4
Zero-speed clamp function”.
Internal speed
Instruction 1
Used to set the speed value of internal speed instruction 2. To use internal speed instruction 1 to 7, you need to
set 3 DI terminals as DI function 13 (INSPD1, internal speed instruction 1) to (INSPD3, internal speed instruction
3). The switch of the internal speed instruction section is realized by controlling the DI terminal logic of the
servo control device. The running instruction segment number is 3-bit binary number. The corresponding
relationships between internal speed instruction 1 to 3 and running segment number are as below.
Internal speed instruction segment number
