Use and maintenance manual
TIGER 370 CNC--MR
TECHNICAL CHARACTERISTICS --- APS/P DRIVE
Power supply
Terminal Name:
+ HV (Positive power supply)
GND (0 V)
Engine connection
PHASE A1 = Phase A1 of the step motor
PHASE A2 = Phase A2 of the step motor
PHASE B1 = Phase B1 of the step motor
PHASE B2 = Phase B2 of the step motor
Outputs
Of a PNP optoinsulated type “open collector” (10 mA max)
Also optoinsulated, so an external power supply (+12V/+24V) must
be connected to the terminal common to the optoinsulators (Pin 12
connector J2). Maximum current for each output (10 mA).
Inputs
Of a PNP type (from 12 Vdc to 24 Vdc)
Not optoinsulated:
jumper JP1 ---inserted
Pin 12 of connector J2 ---connected to +15V auxiliary (pin 21 connector
J2) (common input optoinsulators)
Optoinsulated:
jumper JP1---not inserted
Pin 18 on connector J2 ---connected to GND of outside power supply
(common input optoinsulators)
Protections and safety devices
Protections against short circuits:
--- between outputs
--- between outputs and the positive power supply terminal
If one of the conditions above occurs, the drive will disable the power
bridge, and display the error conditions on the screen:
“u” = wrong power supply voltage value
“t” = thermal protector intervention
“c” = max. current protector intervention. due to a short circuit across
the phases, or excess current.
If the drive is not disabled by a protective device, the display will
indicate the letter “r” (ready).
Thermal protection against overheating
Mains undervoltage and overvoltage safety devices
INPUTS
SIGNAL
FUNCTION
DISABLE
Disables the power bridge (current on motor=0)
CURRENT REDUCTION
Reduces the current on the motor. The percentage reduction can be set
at from 25% to 50% of the regulated current using dip A1.
DIRECTION
Select the direction of rotation. The signal must remain stable for at
least 50 microseconds before and 50 microseconds after the low---high
transition of the STEP---IN signal.
STEP---IN
The motor carries out a step on the low---high transition of this signal.
It is preferable to use a square wave with a duty---cycle of 50 %.
The absence of this signal for 0,5 sec determines the automatic reduc-
tion of the current (stand---by condition). The percentage reduction for
stand---by can be set at 25% or 50% of the regulated current, using dip
A1.
