Chapter 12 Description of Parameter SettingsC2000-HS
12.1-06-6
When you set Pr. 06-06 or Pr. 06-09 to 2 or 4, an ot1 / ot2 warning displays and the drive stops
running after over-torque detection. The drive keeps running after you manually reset it.
Current Limit
Default: 170
Settings 0–175% (100% corresponds to the rated current of the drive)
Sets the maximum output current of the drive. Use Pr.11-17–Pr.11-20 to set the drive’s output
current limit.
When setting the control mode as VF, SVC or VFPG, if the output frequency of the drive reaches
this current limit, the output frequency decreases automatically. It works like the current stall
prevention.
Electronic Thermal Relay Selection (Motor 1)
Electronic Thermal Relay Selection (Motor 2)
Default: 2
Settings 0: Inverter motor (with external forced cooling)
1: Standard motor (motor with fan on the shaft)
2: Disable
Prevents self-cooled motor from overheating under low speed. Use an electronic thermal relay to
limit the drive’s output power.
Setting the parameter to 0 is suitable for an inverter motor (motor fan using an independent
power supply). For this kind of motor, there is no significant correlation between cooling capacity
