Power up the VFD.
2
Press the #1 button on the display one time and the screen will change to a menu listing with scroll mode at the top of
the screen.
3
With “SCROLL MODE” highlighted press the center dot button on the display to enter the “SCROLL MENU”
4
Using the down arrow button highlight “d:Monitor” and press the center dot button to enter the “MONITOR” listing.

ACCELERATION / DECELERATION TIMES
When adjusting the deceleration times be sure to check the hook block limit for over travel. If over travel occurs either lower the
deceleration time or adjust the limit zones.
Changing the acceleration time to a shorter time can cause a E01 over-current or E05 over-load fault /trip, if this occurs due to a short
acceleration time increase the acceleration time and test again.
Changing the deceleration time to a shorter time can cause a E07 over-voltage fault/trip, if this occurs due to a short deceleration
time increase the deceleration time and test again.
Use the chart below to configure the standard acceleration and deceleration times.

ALTERNATE ACCELERATION / DECELERATION TIMES
The alternate acceleration and deceleration function can be used to switch from the standard acceleration and deceleration times to
an alternate acceleration and deceleration time based on a digital i
reverse plugging). If you plan to use switch by input [2CH] you will need to configure an available digital input function for 31:[2CH]
(example CA-06 = 31) and add the 24v circuit for that input.

MICRO-SPEED FUNCTION
Micro-speed is designed to temporarily restrict the speed of the hoist to a lower speed and to prevent high speed operations until the
function is released. The micro-speed function can be configured two ways.
2-STEP MAINTAINED MODE
– This mode will switch to a 2-Step maintained speed set. This is helpful where the micro-speeds need to
be specific. This mode can also be used to provide a single speed by setting the low and high micro speed values the same value. To
use this mode UE-16 must have a value of 0.
PERCENTAGE MODE
– This mode will take the value from UE-16 as a percentage of the standard speed set. Setting UE-16 to a value of
thod.

AUTO-SPEED 90HZ FUNCTION
The auto-speed function will allow the VFD to increase the high speed to 90Hz when there is an empty hook or a light load. You can
set this function for automatic or for input activation. The auto-speed function is not available when using 0-10V/4-20mA speed
control methods, when micro-speed is active, and or when in tandem mode.
HOW IT WORKS –
the VFD will check to see if the load monitor value is less than the auto-ncy to increase to
the auto-
NOTE – While operating in control modes (AA121) sensorless vector control (08), zero speed area sensorless vector control (09), or
vector control with encoder (10) the Auto-

*NOTE – 30% should be the max load for 90 Hz & 60% should be the max load for 75 Hz
2
Navigate to VFD parameter db-14. This will display the load value that will be used to set the auto-speed activation
level.
3
Using the pushbutton or radio, command the hoist in the up/forward direction with high speed and record the value
of VFD parameter db-14 while the load is operating at the high-speed
4
Navigate to VFD parameter UE-21 and set the value to the value recorded from db-14 + 3.
(example db-14 = 37, set UE-21 = 40)
5
Verify the auto-speed function works by lifting the same load at high speed. If the auto-speed function is configured
for automatic then you should see the speed increase to 90hz, if you are using the input activation function then make
sure the input is active and you should see the speed increase to 90hz

/ OVER-WEIGHT BYPASS
-weight signal.
To bypass the over-weight signal, locate the bypass terminal knife disconnect it should be labeled “BPS” (use images below as
reference) and pull the yellow/orange tab to open.
IMPORTANT - Be sure to close the over-weight bypass terminal knife disconnect “BPS” after the load test is complete, failure to do so
may result in damage to the hoist in the case of an overload.
NOTE –
load is suspended or the VFD may fault.
Over-Weight Bypass Knife Disconnect
Page 15
HOIST OVER-WEIGHT FUNCTION
The VFD is setup to use the output current to the motor as the over-weight function. The VFD uses (2) over-weight current
parameters. Over---weight (2) is when operating
above low--weight (1) and over-
Having (2) over-weights greatly increases over-weight accuracy and decreases the likelihood of a false over-weight condition.
The VFD has an alternative over-weight current parameter source that can be configured. This is normally used in applications where
the hoist over-weight needs to be limited to a lower value in certain parts of a building or runway. The alternative over-weight uses (2)
over-weight current parameters in the same configuration as the standard over-weight function. To use the alternative over-weight,
configure the parameters in the chart below and modify the over-weight circuit to switch the source of the signal to the 24v DPDT
relay between digital output 11 and digital output 14.
The VFD has (3) configurations for the over-weight signal, external momentary, external maintained, Internal.
External momentary - will output a signal when the condition is met but will not maintain the output after the condition is no longer
met.
External maintained - will output a signal when the condition is met and maintain the signal until the reset condition is met or power is
cycled.
Internal - s to function. Internal works the same way as the external maintained but will internally
prevent the hoist up function until the reset condition is met or power is cycled.
NOTE
– Internal is only latched to the STANDARD OVER-WEIGHT function.
HOW IT WORKS – When the output current to the motor exceeds the value in the conditional over-weight current parameter for an
amount of time that exceeds the detection delay time, the conditional digital output will turn on and activate a 24v relay to interrupt
the hoist E-Stop circuit. The signal is turn off once the hoist has lowered for 2.0 seconds.

MOTOR THERMAL PROTECTION USING THERMISTOR
The temperature protection of an external device can be made by connecting a thermistor installed in the motor or other external
device to the inverter and setting the function of the thermistor. The external thermistor should be wired between the control
terminals TH+ and TH-. Set the thermistor selection [Cb-40] and the resistance level to cause an error [bb-70] in accordance with the
thermistor’s specifications. When [Cb-40] is set to 02, [dA-38] motor temperature monitor indicates the detected temperature of the
motor.
[E035] thermistor error occurs when the thermistor resistance reaches the thermistor error level [bb-70] depending on the motor
temperature.
To use this function, the wiring distance between the motor and the inverter should be 20 m or shorter. Since the current flowing in
the thermistor is very weak, a measure such as wiring separation should be taken to prevent noise from the motor current.
When [Cb-40] is set to a value other than 02 NTC negative temperature coefficient resistor, [dA-38] motor temperature monitor
indicates 0 °C.

function.
If the shock-load function is activating under normal condition you will need to increment the shock-padder. Be sure to
only increment the shock-padder by a value of 1 until the shock-load function is no longer activating until normal
conditions.

It is rare for field adjustments to be made for any of these parameters. Please consult Detroit Hoist before adjusting any motor brake
parameters.
When switching between VFD Control Modes (AA121) the internal firmware will automatically assign the AL relay function CC-07 to
the default value listed below. Relay 16 can be used in tandem with AL for added safety by changing VFD parameter CC-06 to the
value set in CC-07 and moving the wire from AL1 to 16A and wiring AL1 to 16C.
IMPORTANT – When switching between VFD Control Modes (AA121) the internal program will automatically assign the AL relay
function CC-07 to the default value listed below it does NOT set CC-06 automatically.

The brake release delay time is used to compensate for delayed brakes and help prevent driving through the motor brake.
The brake set delay time is used to compensate for delayed brakes and help prevent nuisance brake slip detection.
