Preface
Based on many applications of Inovance servo drive specialized for the hydraulic pump
system and experts' experience in the industrial control technology, this manual is
complied to help users quickly locate and solve problems.
The manual collects onsite maintenance skills and experience of service personnel of
Inovance and injection molding machine (IMM) manufacturers. It is aimed at helping
users to perform routine maintenance and troubleshooting on Inovance IS300 servo
drive, and quickly locate and rectify basic faults to restore manufacturing.
This manual can also be used as the training material for the service personnel of IMM
manufacturers and help them to find the fault causes timely on site and provide more
professional services.

Chapter 1 Safety Precautions
1. Servo motor insulation test
Perform the insulation test when the servo motor is used for the first time, reused after
being stored for a long time, or in a regular checkup, in order to prevent poor insulation of
servo motor windings from damaging the servo drive. The servo motor must be
disconnected from the servo drive during the insulation test. A 500-V mega-Ohm meter is
recommended for the test. Ensure that the insulation resistance is not less than 5 M.
2. Thermal protection of motor
If the rated capacity of the motor selected does not match that of the servo drive,
especially when the rated power of the servo drive is greater than that of the motor, adjust
the motor protection parameters on the operation panel of the servo drive or install a
thermal relay for the motor for protection.
3. Motor heat and noise
The output of the servo drive is pulse width modulation (PWM) wave with certain
harmonics, and therefore, the temperature rise, noise, and vibration are slightly greater
than those at running with the mains frequency.
4. Voltage-sensitive device or capacitor on the output side of the servo drive
The output of the AC drive is PWM wave. Do not install the capacitor for improving power
factor or lightning protection voltage-sensitive resistor on the output side of AC drive.
Otherwise, the AC drive may suffer transient overcurrent or even be damaged.

Chapter1SafetyPrecautions
4
5. Use outside the rated voltage
The servo drive must not be used outside the allowable voltage range specified in this
manual. Otherwise, components inside the servo drive may be damaged. If required, use
a corresponding voltage step-up or step-down device.
6. Prohibition of changing three-phase input into two-phase input
Do not change three-phase input of the servo drive into two-phase input because this will
cause faults or damage to the servo drive.
7. Surge suppressor
The servo drive has a built-in varistor for suppressing the surge voltage generated when
the inductive loads (electromagnetic contactor, electromagnetic relay, solenoid valve,
electromagnetic coil and electromagnetic brake) around the servo drive are switched on
or off. If the inductive loads generate a very high surge voltage, use a surge suppressor
for the inductive load or use a surge suppressor together with a diode.
Do not connect the surge suppressor on the output side of the servo drive.
8. Altitude and de-rating
In places where the altitude is above 1000 m, the cooling effect reduces due to thin air,
and it is necessary to de-rate the servo drive. Contact the agent or Inovance for technical
support.
9. Special usage
If wiring that is not described in this manual such as common DC bus is applied, contact
the agent or Inovance for technical support.
10. Disposal
The electrolytic capacitors on the main circuits and PCB may explode when they are burnt.
Poisonous gas is generated when the plastic parts are burnt. Treat them as ordinary
industrial waste.

Chapter1SafetyPrecautions
5
11. Adaptable motor
The standard adaptable motor is permanent synchronous servo motor.
The standard parameters of the adaptable motor have been configured inside the servo
drive. It is still necessary to perform motor auto-tuning or modify the default values based
on actual conditions. Otherwise, the running effect and protection performance will be
affected.
The servo drive may alarm or even be damaged when short-circuit exists on cables or
inside the motor. Therefore, perform the insulation short-circuit test when the motor and
cables are newly installed or during routine maintenance. During the test, make sure that
the servo drive is completely disconnected from the testing parts.

2.3 Electrical Wiring
The electrical wiring figures below are aiming at helping the users who initially use the
servo drive to be able to perform the operations described in the troubleshooting process.
2.3.1 Wiring of the External Braking Unit
Two wiring methods are provided, differing in the wiring of braking resistor overheat
protection.
Wiring method 1: After the signal of the braking resistor overheat relay is sent, the power
supply of the IS300 is cut off.
Wiring method 2: The signal of the braking resistor overheat relay is used as input of the
IS300 external fault (Err15).
Figure 3-18 Basic wiring method 1
In this wiring method, the input voltage class of the contactor control coil is 220 VAC. The NC contact of
the thermal relay is connected to the power supply of the wire package driven by the main contactor.
When a fault occurs, the driving power supply of the contactor is cut off to disconnect the main contactor.

3.2 Viewing and Modifying Function Codes
The operation panel of the IS300 adopts three-level menu.
The three-level menu consists of function code group (Level I), function code (Level II),
and function code setting value (level III), as shown in the following figure.
Figure 3-2 Operation procedure on the operation panel
You can return to Level II menu from Level III menu by pressing or . The
difference is as follows:
After you press , the system saves the parameter setting first, and then goes
back to Level II menu and shifts to the next function code.
After you press , the system does not save the parameter setting, but directly
returns to Level II menu and remains at the current function code.
Here is an example of changing the value of F3-02 from 10.00 Hz to 15.00 Hz.
Figure 3-3 Example of changing the parameter value
In Level III menu, if the parameter has no blinking digit, it means that the parameter

cannot be modified. This may be because:
Such a function code is only readable, such as, servo drive model, actually detected
parameter and running record parameter.
Such a function code cannot be modified in the running state and can only be
changed at stop.

frequency.
Start trial running in operation panel
control and monitor whether the output
current is normal and whether the
motor runs stably.
3.4.2 Trial Running Check
1) Check whether the running direction of the servo drive is correct. If not, exchange any
two phases of UVW, re-perform motor auto-tuning and then perform motor trial
running.
2) If the motor runs abnormally, check the motor parameters in group F1 and the setting

of A1-04 (Number of pole pairs of resolver). Then re-perform motor auto-tuning and
perform motor trial running.
3) If the motor oscillates or runs with low frequency noise, weaken the speed loop and
the current loop appropriately. For example, decrease the values of F2-00, F2-03,
F2-13, F2-14, F2-15 and F2-16, and increase the values of F2-01 and F2-04.
4) If the motor rotational speed is not steady, enhance the speed loop and the current
loop appropriately. For example, increase the values of F2-00, F2-03, F2-13, F2-14,
F2-15 and F2-16, and decrease the values of F2-01 and F2-04
The parameters of speed loop and current loop are defined in group F2.
The speed loop and current loop response directly affects pressure stability. Set stronger speed
loop and current loop response if allowed.
3.4.3 Setting and Auto-tuning of Motor Parameters
Parameter Setting
The IS300 controls the servo pump in closed-loop vector control (CLVC) mode. This mode
requires accurate motor parameters. To guarantee good driving performance and running
efficiency, set the motor parameters strictly according to the nameplate of the standard
adaptable motor. The following table lists the parameters to be set.

0: Common asynchronous motor
1: Variable-frequency asynchronous motor
2: PMSM

Auto-tuning
Mode Pr. Setting Application
No operation F1-16 = 0 After motor auto-tuning is completed, the value of F1-16 is
restored to 0 automatically.
Static
auto-tuning 1 F1-16 = 1
This mode is used when the back EMF of the motor is known.
The motor runs at a low speed during auto-tuning, and
therefore, the overflow valve need not be opened.
Dynamic
auto-tuning F1-16 = 2
This mode is used when the back EMF of the motor is
unknown.
The motor runs at a high speed during auto-tuning, and
therefore, the overflow valve must be opened. With-load
auto-tuning reduces the accuracy of motor auto-tuning,
affecting the system control performance.
Static
auto-tuning 2 F1-16 = 3
This mode is used when the back EMF of the motor is known
and there is heavy load.
The motor runs at a low speed during auto-tuning, and
therefore, the overflow valve need not be opened.
When wiring of the encoder and motor is correct but Err43 is
reported, use this mode. Otherwise, the resolver feedback
signal is wrong. In this case, check the encoder signal wiring
and installation accuracy.
