Yaskawa AC Drive Z1000 AC Drive Bypass for HVAC - Manual (Page 12)

Status Description
Open Drive is stopped or one of the following functions is being performed: baseblock, DC Injection Braking, Short Circuit Braking.
Closed Drive is outputting frequency.

Figure i.12 During Frequency Output Time Chart
Setting 39: Watt Hour Pulse Output
Outputs a pulse to indicate the watt hours.
Setting 3D: During Speed Search
The output terminal closes while Speed Search is being performed.
Setting 4C: During Fast Stop
The output terminal closes when a Fast Stop is being executed. .
Setting 4D: oH Pre-Alarm Time Limit
The output terminal closes when the drive is reducing the speed due to a drive overheat alarm (L8-03 = 4) and the overheat
alarm has not disappeared after 10 frequency reduction operation cycles.
Setting 60: Internal Cooling Fan Alarm
The output closes when the drive internal cooling fan has failed.
Setting 100 to 160: Functions 0 to 60 with Inverse Output
These settings have the same function as settings 0 to 60, but with inverse output. Set as 1oo, where the “1” indicates inverse
output and the last two digits specify the setting number of the function.
Examples:
• Set 108 for inverse output of “8: During Baseblock 1 (N.O.)”.
• Set 14D for inverse output of “4D: oH Pre-Alarm Time Limit”.
u L6: Torque Detection
n L6-01: Torque Detection Selection 1
The torque detection function is triggered when the current or torque exceed the levels set to L6-02 for longer than the time
set to L6-03. L6-01 selects the conditions for detection and the operation that follows.
Note: Parameter is available in bypass controller software versions VST800298 and later.

Torque Detection Selection 1 0 to 8 0
Setting 0: Disabled
Setting 1: oL3 at Speed Agree (Alarm)
Overtorque detection is active only when the output speed is equal to the frequency reference (i.e., no detection during
acceleration and deceleration). The operation continues after detecting overtorque and triggering an oL3 alarm.
