5.7.5 Test Mode
Test Mode is a troubleshooting aid that is intended for troubleshooting Flux Vector problems. The feature cannot be
left on indefinitely as it will generate a fault after being on for a total accumulated time of 10 minutes. At this time,
the fault must be reset or power must be cycled.
When enabled, the Control Method in A01-02 is temporarily overridden to V/f. All other functions for the new control
method are not restricted. Certain programming may need to be done to clear up any OPE conditions that may
occur as a result of the change in control method during this mode. It is up to the user to determine if a special
function may cause an unsafe condition during testing. Since this feature will be used mainly for No-Load Brake
type hoists, many of the inherent safety checks will become disabled. It may be desirable to disable functions such
as Ultra-Lift, but desirable to leave Limit Switch functions enabled. The user will need to determine what functions
are being used. If unsure, it is best to ensure that the function is disabled (either by programming or MFDI in OFF
state) before running the VFD/motor in this mode.

5.7.6 Torque Detection
The overtorque detection circuit activates when the motor load causes the motor current to exceed the overtorque
detection level (L06-02). When an overtorque condition is detected, alarm signals can be sent to a multi-function
output. To output an overtorque detection signal, select torque detection 1 at either of the multi-function digital
outputs (H02-0x = “B” or “18”).

Parameter Display Function Range Default
L05-01 Test Mode Test Mode Enable. Starts a 10 minute timer
after which the VFD will not function until Test
Mode is disabled. If power is cycled, Test
Mode will become disabled.
When test mode is enabled, Test Mode
settings will be used for operation. Refer to
the E03 group.
